Interlux Brightside

I chose the Primekote 404/414 as primer because, at the time, I had not decided between Brightside and Perfection.  I have long referred to Perfection as 'the poor man's Awlgrip' and to Brightside as 'the poor man's Perfection'.  All three share similar qualities: they are rugged, hold up well to UV and to seawater, go on very well with a minimum of application effort (just roll on and take care) and are somewhat compatible in that primer for any one of them can be used with the lower grades of paint.  If you can't afford Awlgrip or a guy like Jeremiah at CY to apply it for you, your next bet is to apply the two-part epoxy Primekote and then pick either Perfection or Brightside.

Jerry, from the C44 Second Alarm, has been my boatyard neighbor for two seasons now.  He very generously offered to assist me with the application and did most of the rolling of both the Primekote and the Brightside himself.  I defer to his expertise in applying surface finishes as he's completely redone the hull of his 1981 boat from bare fiberglass to finish gelcoat, almost entirely on his own.  We readily share concerns, advice and encouragement and so he was a natural and welcome partner in this vital chore for Diana.

Taking the time to do it now

I took the better part of two days off from work for this.  To some this sounds irresponsible; but, to me, a boat is like a pet.  If it needs you now, it needs you now; and you are irresponsible to put it off till a situation becomes unhealthy.  I don't consider boats mere things, like that.  They have spirits and souls and feelings and needs.  Sail one and you know what I'm talking about.  I saw it during the Sandy storm-- with 68,000 boats in New Jersey having insurance claims filed, you just know that some of them were owned by people who said, 'It's only a boat.  It's insured.'  I could use the money anyway.'

Forgive the harsh opinion; but these people clog up the insurance-claim process and annoy and delay those of us who truly care.  I saw BOATUS and many others come through like knights in shining armor for boat owners who truly cared-- and I worked very hard on restoring several of those boats myself, if only because of two things:

1. I know what you feel like when your boat needs work, since I love my boat as much as you love yours.

2. I want to see your boat happy and sailing again as much as I want to see mine happy and sailing again.  This is what I do, and this is why I do it.

So I was grateful to Jerry for his help but I knew he knows how I feel about it because I know he feels the same way about his boat.

Brightside lessons

Since this is me, I have to delve into the bad news first!

I uploaded these two pics in a large format to illustrate how the first coat of Brightside goes on.  Formerly both of these places on Diana were repaired, using a combination of Evercoat 27 and WEST epoxy with filler.  The first one, below, had some significant pitting in the gelcoat and, being on the shaded, close-quartered side of the boat when it was in The Swamp, I did not get the chance to finish fairing these.  In truth I didn't really see them that well there.  So Jerry and I decided, what the heck? --and we painted over them to see what we'd get.  I don't think you can notice in this picture but the Brightside does not cover imperfections very well, if at all.

So, Lesson #1 with using Brightside:

It is not latex house paint.  It is not 'high hiding'.  It changes the color and seals the surface; it does not fill divots at all.

The second pic, below, illustrates what I call 'the thin white panties problem'.  (You get no further explanation of the name.)  This was where I filled the factory-installed galley-sink drain hole (relocating it, with seacock, to the bilge).  I was anxious to see how well Brightside would cover over darker-colored stuff like the WEST epoxy with gray and tan filler in it.  The result was that one coat did pretty well.  This would disappear completely on the second coat.

So, Lesson #2 with using Brightside:
It does change color; but when it's white over dark, it'll take two coats.  This is in line with pretty much any other paint; but here I believe it is a factor of the thin application layer of Brightside.  You don't put it on thick; you do multiple coats.  (In other words, it's not Bilgekote!)

At the end of the day, the guys from the shop were coming out and saying things like 'Hey!  John has a shiny boat now!'  I doubt they realized what this meant to me-- it may be the first time I have received any kudos from others on my work with this boat at all.  Naturally I replied that it was all down to Jerry-- for his constant encouragement, invaluable assistance and almost-paternal admonishing me to keep moving.  This is a guy who supervises urban firemen-- he knows how to motivate people and in my case has done it well.

We got the second coat done the following day, after I spent the whole morning (18-20 hours' drying time) sanding this coat with 320.  We had one egregious error (mine, I am sure) where we had to retouch a place where I missed tipping (probably due to intense sun glare that side).  The attempt to get it on and all smooth was not successful.  It ended up being covered but as a lump that looks like a bulkhead pressing through.

So, Lesson #3 with Brightside:
You have about five minutes, and no more, to finish rolling and tipping applied paint.  Don't hesitate-- get it right now, and keep moving on.  You won't be able to go back and fix it; it'll mean another whole coat if you let it go.

This is all well anyway, as I'd like to redo a few places on the transom and resolve the matter of a few divots.  I'll do the third coat in the spring (as well as another barrier coat on the bottom).  For now, Diana's going under a shrink-wrapped cover so I can focus on the engine, the electrical system, and a few odds and ends that can be fit to the boat and finished in the shop.

Thanks again to Jerry for all his work; for this is really all down to him here.

Replacement cockpit drains - Take Two

18-19 July 2014

I don't think I mentioned this before, so....

The small brass fittings I installed about two seasons ago (here) were really too small.  After making a big deal out of putting them in, I decided to replace them with the very idea I have been advising other H25 owners to do for many years.

The original H25 drains were RC Marelon through-hulls straight out the back wall of the cockpit-- necessitating that water either climb up the 5/8" threshold to flow out or else stay in the cockpit pan.  I installed the little brass drains in the sole itself, fitted them with 90-degree elbows and though them good enough.  After consulting with my friend Roland (SV Moonshine) about his solo Atlantic crossing, I decided too big can never be big enough.

The fix I have been long suggesting for this entails the fitting of a rigid fiberglass tube straight out the very bottom corner of the cockpit pan through the transom.  In what has to be the most productive two two-hour work sessions I have ever had on this boat (even in the face of predicted rain), I drilled the holes, bedded these into place, removed the old ones and filled and faired the old holes.  I did one one day and one the next, after a full day of work each time.  It impressed even myself!

 

Here's the view from the cockpit.  The tubes are 1" inside, 1-1/4" outside diameter, pressed fiberglass, ordered from McMaster-Carr.  It was about $21 for one 60-inch piece, which, cut in half, fit perfectly for this application.  I deliberately made the cut on an angle, twisting each tube in its hole in order to fill the corner (shorter side inboard).  Bedded in 5200 and faired with WEST epoxy and Microlight, they look like they were molded there.

 

At the transom I allowed the excess length to just stick out and, when the epoxy had dried, cut them shorter with a hacksaw and used the orbital sander to smooth them over.  This picture doesn't show it so well, but the factory's installation wasn't symmetrical-- one old hole (filled as of this picture) will appear closer to the new tube than the other side.  I just eyeballed the site from above, applied a ruler and made them lead  out parallel to the centerline, straight aft from the corners of the cockpit pan.

The green tape covers the HIN.  I got some epoxy into it a while ago and decided to preclude any more messing it up.

The other two through-hulls are the Marelon ones I installed for the bilge pumps.

 

Looking under the cockpit the downward angle and parallel leads are seen clearly.  The duct tape is part of one of my 'mooyock' solutions for filling holes.  When the old through-hulls were taken out (with hammer and chisel), I taped over the holes in the inside and made up 'communion wafers' of fiberglass to stuff into the voids from the outside with epoxy.  Why try to fill a hole that's overhead or angled so that the epoxy will only dribble out?

This isn't a great view of it, but below the tubes is a little floor I installed aft of the low bulkhead in the foreground.  This low bulkhead, a little higher than the waterline, will contain water from any rudder-post leaks in the event of a rudder strike (which should be high on the list of any sailor's worst nightmares).  A small hole, here seen stained in epoxy, is fitted with a brass tube which will accommodate one of those little rubber transom-drain plugs.  It's not the most secure arrangement; but it's much better than having nothing at all in the event of this happening, for which Stephen Dashew says your best scenario is to crack the rudder blade.  Any other possibility involves catastrophic damage to the hull-- and, with your average production spade-rudder boat, probably the end of your voyage.

 

This pic, with the fuel tank in place, shows the upper end of the cockpit-drain tube.  With the little brass things in place, there had to be an elbow over the back edge of the tank that seriously complicated attaching fuel hoses and intruded on space for removing the tank.  Now this is practically structural-- no worries for stuff in the lazzarette weighting down the drain hoses till they fail or pop off.

(The dark spot on the tank is an old epoxy spill, not a leak or any damage.  This tank has been kicking about this boat for very long, getting dusty and spilled-upon, and only now (September) is is finally in its place for good.  Of course I've kept all the openings well taped-up!)

Finally! --it's paint.

9-10 October 2014

I have been procrastinating the hull paint on this boat for an inordinate time.  This is really 'just because' --I truly haven't felt like investing the time and effort into it till now.  But I've had the gallon kit of Interlux Primekote for a while, just for when I decided to do it, and so I finally bowed to the constant encouragement of my friend and boatyard neighbor Jerry (C44 Second Alarm) and together we attacked this.

 

(The spots on the bottom are my repair of some hull cracks that had spread through the Pettit Protect barrier coating that I applied last year.  Discovering these was distressing; but I've been determined to have this boat done properly and so the Dremel took was applied right through it and WEST epoxy, with milled fibers as filler, was troweled into the gouges.  As of now it's really pretty good.)

 

Jerry did the rolling and I was going to try tipping it, for which I bought a couple of really good brushes, but we found that Primekote doesn't want to be tipped.  We also found that it should be thinned more than the 20% the label advises-- I approximated about 25% (or a little more) into each batch.  We mixed 5 batches of about 20 ounces each and this did a little more than two full coats of the hull.  Jerry was a champion with the rolling and really made the paint spread well with virtually no heavy spots.

 

Earlier pics will show the extensive repair on the transom.  Upon removing the center-mounted backstay tang, I discovered its load had sort of impressed upon the transom, creating a hollow.  I filled this with new 'glass and plenty of WEST epoxy with Microlight.  With Jerry's help I sanded the entire hull with 80 grit, and then 120 grit, using DryGuide, this marvelous black powder that, applied to the hull before sanding, illustrates clearly where your highs and lows are.  Sand it all off and it's fair-- and, amazingly, that stuff does not lie.  This hull is incredibly fair-- and, in some places, fairer than it was fresh from the factory!

 

I haven't seen this transom all one color since I brought the boat up to Delran!

 

This poor boat had numerous close encounters with pilings and the like, to the point where some PO cut off a section of bow rail to effect a repair.  I took this off again to repair his repair and left it off for the painting.  By some odd coincidence this is the very section of rail that needs to be cut down to accommodate the anchor roller (as it's tradition for sailboats to have the primary anchor rode to starboard).  The whole nose has been redone with 'glass, Microlight, milled fibres, and endless sanding.  Now in the bright white Primekote it looks almost done.

The holes formerly occupied by the hull-mounted running lights will be fitted with teardrop-shaped black Plexiglas windows, giving light to the forepeak locker and finishing off the bow in a familiar way.  I'm putting little blue LED lights in here (called 'docking lights' on the breaker panel) to represent Diana's personality.

JC's secret system for filling deck-core rot

I recently posted a comment responding to a core-fixing issue on the Hunter Owners Web.  I think this is valuable for most fiberglass-boat owners to consider.  Here is the whole text.

-----------------------------------------------------------------------------------------

JC:

I filled all of the 'rotted'/'questionable'-core spots on my deck with epoxy. It's so rigid you could hold a teenagers' hip-hop dance party on it.

Once I made a mistake and began filling too close after a rainstorm. I don't know what I was thinking; but when I [pumped with the syringe] I saw that the epoxy actually pushed the water up to the surface. I was very surprised-- thought I had wandered into a really fine mess. What I found was that by continuing to inject epoxy, the ugly baby-vomit-looking water/epoxy slime that migrated upwards eventually stopped-- all the water (and not very much had ever got in) was gone and now the epoxy was doing its job, saturating to the bottom of the void and filling towards the top. The result was a deck area as stiff as any of the other places I have filled.

The only drawbacks to my system of 'drilling and filling' is that epoxy weighs more than does foam or balsa. In very large repairs the weight difference could be a problem. In my 40 years of boatbuilding experience I have never found a point at which this is a problem. The sides of a small production sailboat's cabin are just not enough volume to warrant worry about any increase in weight. The average owner's toolbox would probably negate any theoretical savings.

While it is very true that 'Water migrates very far from the point of entry' [mentioned by the original poster], it is also true that epoxy does the same thing, perhaps even better than does water. Penetrating epoxy is made to do this. I have been filling voids successfully with epoxy since I first heard of the stuff in the 1970s and the only significant mess I ever encountered was when the epoxy would not seem to stop sucking in, and more and more got pumped in with the syringe, until I happened to notice an uninstalled drawer sitting in the pilot-berth area with one whole corner full of the stuff. Through the tiny voids between plywood edge-grain and the fiberglass, the epoxy had migrated 10 or 12 feet along the flange of the boat (and fortunately found something to drip into that was more or less replaceable). To this day that part of the flange on that boat is probably the strongest hull-deck joint we've ever had on one of those boats.

I would trust WEST epoxy with any wood-to-wood or wood-to-raw-fiberglass joint with my life-- and, oh, wait-- I do; because my boat has been restored, remodeled and improved based on that ethic.

 

-------------------------------------------------------------------------------------

A friend, Pilot, then asked me:

'Can you describe the process and the materials you would use. Specifically the typical hole size drilled the distance between holes and the number of holes for a given area. I've read other articles for epoxy injection but would like a builders take on this process.

'My boat was surveyed 3 years ago and an area around the windlass was found to have an elevated moisture level. Rather than pull the windlass and start replacing plywood core and all that's involved in that, injecting may be the solution that stems the moisture migration and solidifies the deck.

'My own personal thoughts on wet core and soft decks is, it's a distraction, and after 37 years of sailing on many different boats some that I've owned I have never seen a catastrophic failure based on moisture or soft decks.'

----------------------------------------------------------------------------------------

So I told him (writing a veritable book into the process!):

If you know there is water present you can drill a hole-- only through the fiberglass layer(s)-- from one side or the other and then apply a vacuum hose to suck it out. This works surprisingly well-- it's the first step I recommend in fixing rotted outboard-skiff transoms. They all rot (motorboaters don't seem to care for their boats like we do ours); and this is the best way to save them. (I am doing my motor bracket's backing board the same way.) You then drill a few smaller holes, sized to fit the syringe, maybe about 3/16" or 1/4", into the top of the transom and pump in the stuff.

I used to thin the epoxy with acetone (not what Gougeon Brothers recommend; though when I told of them of this they said 'Who are we to argue with the Cherubinis about treating wood?" ) But you really do not need to thin it; as it's only doing its job by penetrating the way it does.

You might go cautiously at first, with just a little (3-5 pumps' worth?)-- it will migrate down. When it comes out the hole you drilled for the water, at the bottom, you know it's done what it should (and you know the transom was toast). Next batch, tape over the hole and after it's kicked off, go for broke and really pump it in.

For a deck, you do basically the same thing. You might drill a hole into the underside for your vacuum hose. Tape it securely to make an 'airtight' seal-- I have done this adequately enough with duct tape-- and run it till the vacuum cleaner's motor labors. For Diana I knew the deck to be already dried-out (but for a mistake involving a recent rain, as I said). Be sure to plug up or tape over any openings in the underside-- for the epoxy will definitely find them. You might station a partner below to watch for drips! --and be very wary of when you are pumping in tons of epoxy and apparently making no progress! Spots to watch are along the flange/toerail seam and anywhere silcone (or something worse) was used to bed down through-bolted deck hardware.

Topside, you drill a few holes to begin (you can always drill more if you think you have to). The best tactic is to choose a spot, maybe a few square feet and outboard (low) on the deck, drill pilot holes-- into the core only (mark the bitt with tape if you're worried, to be sure)-- near the highest border of the spot, and fill till you see the epoxy is no longer soaking down in your pilot holes. Don't make the mistake I've made too many times and go silly drilling too many holes-- when the epoxy makes it down to the lower holes you get a dribbling mess all over.

I generally make the holes about 4 inches apart; but it depends on the size of the area you are working with and how serious the rot is inside the core. In theory even rotted core is still 'there'; and epoxy will bond very well with wood or foam dust. As I said before, it is heavier than core material; but as I said too it's never been a terrible concern in the proportions we're talking about. For odd isolated areas it is a very solid, reliable, permanent fix. And if you do not get it all, the parts you do get remain strong and make a good base or boundary for you to fill other places.

If you choose to drill only in places where there is nonskid, you have only to fair over the holes and repaint the nonskid patches. For my deck, which was pretty bad, I resigned myself to repainting the whole deck (with Perfection) and I was redesigning the pattern of the nonskid patches anyway. The little indentations left when the epoxy is done flowing in can be faired with Marine-Tex or epoxy with silica gel, either of which will be rugged enough to not fall out in future and will be able to take paint (after the usual proper prep). Gelcoat, being polyester-based, will not stick well to epoxy (though the reverse is true). So in using epoxy you've pretty much given over the hope of refairing the affected area in polyester- (or vinylester-) based products.

This system should also be used any time you have to mount or re-mount hardware to a cored deck. Drill a pilot hole-- only through the fiberglass to the core-- for each mounting screw and fill it. Do the same in the area under the bit of hardware, like a winch and especially anything in compression or tension, like a padeye or halyard-lead block. When it's cured, drill through the solid-epoxy core you've just filled and bed down the part with 5200-- which will keep out water, hold like crazy especially in shear or tension, and provide needed flexibility. In many cases you will need only fair-sized fender washers with the under-deck locknuts because the epoxy block you just made can serve as an adequate backing plate, especially for anything in shear, like cleats and halyard stoppers.

I had doubts about the integrity of my hull after I rebedded the keel and so drilled a few exploratory holes into the bottom strata, between the keel bolts, to probe them with epoxy. This was supposed to be only solid fiberglass; and it was. No hole took more than a fraction of the syringe's worth. It was-- and is-- solid.

For Diana I had made a new, short little bulkhead at the back end of the cabin sole on which I stood the ladder/cooler shelf structure. I used 'high-quality' 3/4" MDO for it. Within too short a time this board was rotten from water behind it (from the cockpit-seat locker leaks), even though it had been well saturated (so I thought) before I installed it. (I blame it on using Dave's MAS and not my own WEST epoxy. MAS just does not penetrate as well; period.) Removing the bulkhead was out of the question; and it could not stay like it was. I drilled pilot holes down into the top edge of the plywood, straight into the depths of the laminations, just like I would have done for a plywood motorboat transom, and poured in the epoxy. It took three or four tries and made an awful mess (the stuff ran straight through the spoiled core and gushed out the bottom edge, finding gaps in the 5200 and dribbling into the bilge, where it glued down a stray PVC fitting that I still haven't ground completely away) but I sorted it and now it's solid.

I think this is a good solution for your [Pilot's] windlass mounting bolts. Given enough epoxy in the surrounding core, it will take the very severe shock and shear loads very well. Once epoxy has found something to latch onto-- the rough inner surface of the fiberglass deck, the rotten core, the remnants of any plywood-- it will stay in place and provide a very sturdy inner stratum through which you can drill even big bolt holes. And it takes 5200 very well, adds stiffness, and displaces all gaps that might otherwise find condensation or stray moisture. The one thing it does not do well is flex-- but for a windlass mount you had better not have much flex (let the nylon rode take the shock loads!) and a rigid deck is always stronger and thus more secure underfoot than one that moves and flexes to the point of fatiguing the glass fibers within and weirds you out when you step on something you'd prefer to feel solid.

Epoxy and wood = perfect together.  :)
