I've really wondered how this Appliance Epoxy stuff would hold up. It comes in both spray and cans.
Krylon Appliance Epoxy Paint White, Size: 16 oz, Net Wt: 12.5 oz
I used it on the plywood walls of my head instead of putting white veneer back on them. It's lasted three years so far. I doubt it has any UV protection in it, though.
Yeah I actually saw a couple of guys talking about using that stuff on their hulls. They say it worked.
But, judging by the black spraypaint I used on just the castings (it took 3 cans for 4 coats just on those 6 pieces!) - it would take a few cases of cans for both hulls. Then you have to deal with the scratches.
The numbers and durability seem to keep pointing to the gelcoat. One and done.
