You're correct. It's a two part resin, Resourcinol dries kind of dark red/magenta colored. It is sometimes used on those weird cone shaped buildings the state uses to store salt and ash/coal for the roads in the winter. That line it leaves is VERY difficult to prevent, no matter how even and smooth the surfaces are.
I'd prefer to use a clear epoxy or resin with any wood working I do for that very reason but I wasn't really sure what kind of marine epoxy I should use. I will check into the ones you have listed.
Lately I have been experimenting with the titebond 3 and so far, I am fairly happy with it's results, plus it is uber cheap and that is a real plus.
The clear epoxies however would be better for me overall as a true waterproof slealant that will also allow the grain of the wood to show through and be tough as nails at the same time, generally for that I use hellsman spar urethane and was thinking about coating the brush handls with that.
Good idea? or should I use the marine epoxy for everything?
