Re: Painting Formica
Single part paint or primer doesn't stick well to formica because it's scratch resistant and has a non-porous plastic resin surface. It helps to send it well with 80 or 120 grit instead of something smoother. After cleaning with alcohol I use a two-part primer like Epoxy Primecoat, sand it and then ...

Re: Allied Seawind 30 Integral Water Tank Build
Looks good. I don't see any benefit to adding trim. If the trim is trying to hide a rough fiberglass joint I'd prefer to use fairing compound and sand it smooth. If you varnish the trim then you'll keep varnishing since it gets wear underfoot and traps dirt at the edges. But all that is just persona...

That is impressive weight for a 10' dinghy hull. He claims a 25% weight reduction from plywood, even though he used a plywood transom so that's good to know.
