Actually last time I used the rustoleum farm implement gloss white with hardner,,,,, Guy at tractor supply said it would stand up to just about anything....

I used the sherwin williams macropoxy and am very happy brush or roll on goes on great flattens out no brush marks 1 coat. Gal of epoxy and gal hardener about $200. Enough to do 2-3 bilges

I did interlux Bilge coat in the Fountain about 3 years ago. Holding up great

I have used rustoleum with Valspar enamel hardener (you must use that hardener) for almost a decade now. The stuff is great, cheap and easy to find. If you want the off-white fiberglass color in a lot of boats just mix 3qts of white with a qt of their almond. Another thing, the cans of spray paint at depot matches the gallon perfect. Make touch ups easier.
Only one draw back, If you mix the Rustoleum with the hardener you MUST NOT SPRAY IT unless you have a full body suit and a fresh air supply. There is something in the hardener that when sprayed can kill you if inhaled and can even be absorbed through the skin. It only applies to spraying.

Excellent budget friendly option...
