Another post filled with exceedingly helpful info -- thank you! And FGCI looks like a comprehensive & reasonably priced source (even at retail) for one-stop shopping.

I was under the impression that removing wax required more than just alcohol (or acetone?) plus sanding to remove, and one had to use special wax removal solvents. In any event, an additional step (but not all that cumbersome).

That is alcohol and a SCOTCHBRIGHT PAD...meaning one of the rough green ones that you can sand paint with and remove gloss. You will get masses of white chalking once the wax is gone. Gel should not be waxed, it should be compounded to a polish. Yours was beyond help of either one.


Wanna use an official wax remover? More power to you. Those are just citric acid, AKA Koolaid powder or "bug juice". Those work as well, but they also eat the calcium in the talc fillers in your gelcoat. Acids are not great for gelcoat, but not a worry at this point. Just "de-acid" after using.


If you have every used something like "polycoat", then basically you have not waxed your boat, but instead wiped on a thin coat of polyurethane clear single part "varnish". Sanding takes that off too. Sanding with 150 grit with the big electric DA I mentioned really takes no time at all. Catch the edges with that scotchbrite pad, and you are good. In any case, the epoxy will simply serve to make any leftover dirt part of your deck. If chunks of stuff float up out of the epoxy, that means you get to scrape them down again.


NOTE: Get a small (few square feet) piece of smooth cabinet-grade plywood. Wipe a thin coat of polyurethane varnish as a sealer to simulate the surface you will be working with. On one side, practice pouring and spreading/rolling/tipping/painting the epoxy. "Tabletop" epoxy is a little more expensive, but self-levels even better, so you might try that if you can't get good results. Once you are done, try painting your test piece.
Finally, flip it over and try the non-skid application.


-And if you are on the West Coast of Florida, invite me by to help if you need...

That's more than my boat cost.
