(thinking about) gel coating my transom

You gotta love project creep.

The '79 Albin Vega I'm refitting has one small spot on the transom where the gel coat was getting thin. It's quite good and thick almost everywhere else. No problem says I, I'll just do a spot repair. But precisely matching the hull color is vexing me, and with each unsuccessful attempt I'm doing a larger and larger area. So I'm thinking about just re-doing the whole transom and be done with it. I want the transom nice, since that's what other boats will see the most of. :)

I've done a good bit of small gelcoat spot repairs with waxed Evercoat one-step from Jamestown, and a variety of applicators, from a Q-tip to a 2" foam roller to a Preval sprayer. But this is a larger area. Should I invest in a "real" spray gun? If so, any recommendations on a gun? I don't want to spend more than I have to, since I'll probably never use it again, but I also know the perils of spending too little. I could use a foam roller, but something tells me it will have a special set of problems over an area this size.

Gene... google a company called TCP Global. They are a web based Paint & Supply Distributor, lucky for me the brick and mortar storefront is here in SD. I've bought several things there including a nice spray gun and their prices are very competitive for non-crap but still affordable.
Worst case, I think you'd be fine foam rolling the transom. 2 or 3 coats and then wet sanding should handle any issues. But if a good gun is less than say $60 you save yourself time and sweat equity.

BTW... Pics or it didn't happen!

the ft lauderdale location has computer color matching for gelkote. I paid 45 / pint with wax. take a hatch or whatever and they match it (or very very close).

I have also use 'preval' spayers, for small gelkote jobs. it kinda spits the gelkote and blends as it runs. (like a bad rattle can paint job) a real sprayer will work a lot better, but takes a lot of acetone and time to clean up.

You could not have asked this question at a better time! I just bought a project boat, and I am planning to repair many little spider cracks and recoat the deck. Since there are so many, I figured I would just redo the whole deck. Sounds like a sprayer would come in handy.

If you re-spray over the top of spider cracks they will just reappear and you will tear your hair out. Spider cracks have to be ground down to the laminate (not real deep), an engraving bit on a dremel tool works well for this. To fix, don't use liquid gelcoat, use gel-paste (basically thickened gel coat). Go to the Spectrum Color website, they sell 2oz jars of color-matched gelcoat paste, just search for your make/year boat and they should have it. $25 for the jar and 2 oz goes a long way, very easy to work with. After you repair the spider cracks with that gel paste you could be done, but if you want to re-spray to freshen up the whole boat, that would be the time to do it.

Yes. I know they must be ground out and filled. Thanks! I think whomever owned the boat before must have been HUGE!
