    Interlux Perfection Paint Color - White

    I'm planning to paint my transom this spring with Interlux Perfection 2-part paint.

    Anybody have any experience (good or bad) with a close white color match for our aged white gelcoat? The available Interlux color cards vary a lot based on the computer screen and printer settings so it's hard to gauge what the slightly off white colors really look like.

    Thanks!

    Yes. A color chart/brochure/card from Awlgrip (or somebody ) is much better. I mean, printed by them, not on a computer.

    When I had mine painted I taped the color chart to the transom for a couple of days--the difference in effect is quite different when cloudy/in morning/ at sunset. I worried the usual amount + .37 percent and then picked the best compromise.

    Turned out fine. Hardly mattered, in fact, since you can't see the hull and the transom at the same time anyhow.

    Or, more accurately, the light is never reflected the same from the different angles of the surfaces, so the character of "white" is always a little different. The human eye expects that, and accommodates it automatically. I think.

    We left the boarding ladder on and just taped it off.

    [added later: I hired a pro because I have never used Awlgrip. He prepped as I would have, painted at 4 p.m., and dew ruined the job. He started over in morning, sanding again, and got it right. I watched most of his work. He charged $300, which isn;t much. But--hey, I could've done it myself. Next time, I will. ]

    I painted my transom last year with stock Perfection White and it came out wonderfully. It is considerably brighter than the old gelcoat but as Christian says you never see any other part of the boat on the same plane as the transom, so I didn't particularly care how close the various whites were.

    A tip - my transom had a few chips and cracks around the edges, which I filled with two-part chip filler. This is epoxy that has been factory-tweaked to cure to about the same hardness as gelcoat, so you can sand it flush without worrying about oversanding the surrounding gelcoat.

    I wrapped a one-inch strip of Perfection around the edge of the transom too, a racing stripe of sorts, because I will at some point be painting the hull and the chipfilling process would have required some paint on the hull edge of the repair anyway.

    Thanks guys,

    I got the free Interlux Boat Paint Guide brochure and paint color card at the Edgewater (Annapolis) West Marine. The big local marine store Fawcetts also had it. It is also available from Jamestown Distributors for free if you order anything from them.

    The colors on the Interlux color card are very different from my home printed version(s). You must have the factory color card to make a color match.

    I've eliminated all but four of the whites just looking at the chips (too yellow and too brown). I also know from gelcoat matching filled holes that darker is less noticeable than too white so the whitest white (Snow White) is out. I'm left with the four greyish whites Mediterranean, Matterhorn, Artic and Off-white. I agree that actual color match on the transom is not necessary so any of these would work fine. I'll report back when I select a color after I compare these four colors to my gelcoat.

    I found reading about other painter's experience painting with Interlux Perfection on several online forums was very helpful. I also bought Russel Brown's ebook Rolling Perfection from Port Townsend Watercraft for $3.50:

    Off White is the color for me

    I've selected Off White as the color for my Interlux Perfection paint of my transom. I'm currently prepping by removing unused hardware and filling the holes. I've also got remove the glue residue from the vinyl name graphic. After this is filling gelcoat chips and cracks, then fairing and then priming. The limiting factor so far has been the temperatures. The primer can be applied down to 50 degrees but most sources say not to apply the Perfection below 70 degrees with near 80 being perfect. March highs in Annapolis average 50 on Mar 1 rising to 60 on Mar 31. I'm going to prep in the next week and then hope for a few above average days in early April. I don't want to go past April and I'm blocking two other boats in. We all said we'd be ready to launch in early April but I haven't seen anyone working on the other boats yet. I'm ready except for painting the transom.

    It's hard to see the cracking old paint and/or gelcoat in the pictures. The name graphic hides a lot and distracts your eye from ugly the little details. Photo with ghost name in glue is current. Photo with no name is from 2011 when I bought the boat. More to follow.

    Transom Primer

    I've filled all the chips on the transom with thickened epoxy. There were also a lot of chips and old repairs along the edges of the transom. My boat had a windvane in it's earlier life. The transom had been re-gelcoated in the past, probably after the windvane was removed. It now has a couple of areas where the new gelcoat was put on too thick and it is now shrunken and cracked. The upper port corner and the stbd edge have a brownish discoloring. My 7 year old 'GLIDE' vinyl graphic has seen better days.

    I've got one coat of Interlux Epoxy PrimeKote primer (which is white) on in the last picture. You need to thin this paint at least 25% for the first coat so it doesn't cover great but it did fill in most of the gelcoat cracks (which it is supposed to do). It barely covered the dark red epoxy repairs on the first coat. I'm practicing with the primer, thinning it heavily so it flows out smooth using just a foam roller. I needed to thin even more than I did. It was very low humidity and only about 50 degrees which is the minimum to apply the primer. The transom was 60 degrees and in the sun when I put up a tarp/sunshade to paint under. You need to sand between coats of the primer so mistakes can be smoothed out.

    The Interlux Perfection needs to be super thin to flow out to the intended high gloss. It's really only the final coat (of probably 3) that needs to be near perfect so I have a couple of coats to practice in the next few days.

    Looks like it's coming along. We were on the water today in Annapolis and it started out 30F with 14 kt wind but the afternoon was into the low 50s with a lot less wind to loft dirt into new paint. In a couple of days you ought to be golden.

    I've got three coats of primer on the transom and I have found that I still have a few gelcoat cracks showing through. I also found a few small dents and chips that I missed. Time has run out for launching and weather wasn't great for the final topcoat so I am stopping at three coats of primer. The transom looks a whole lot better all one color. I'll probably sand and fill the final cracks and chips at my slip in the water and then decide when to paint my final coat of primer and what to do about the topcoat.

    Painting the primer was good practice for the topcoat. It has some small stipple that I'll have to sand out. I should have thinned the primer even more than the minimum 25%. I thinned even more for the small areas I had to brush and the primer flowed out much better but it would have smoothed out more if it was thinner. I was painting at 50-65 degrees which might be a little cool for the Perfection topcoat. I used a thin foam roller (3 inch) and did not tip with a brush. I used a shade tarp for a few coats when it wasn't windy and it helped slow down drying which keeps a wet edge and it made it easier to see the wet white paint on the previous white coat.

    As has been mentioned by others and you can see in the second picture, the actual color of the transom isn't critical because of the different light angles. The primer is a much brighter white than my gelcoat. If I had my big 'GLIDE' graphic on top of the primer you would hardly notice the color. The Perfection, when applied well, is super smooth and glossy which would be a great match to well polished gelcoat.
