Rustoleum here. I got it from Lowes, straight up bright white. I did not use a hardener, and a half gallon did the entire bilge twice (in my 242). Hard as a rock and looks great! I've had the engine in and out twice, walked all over over it, dropped stuff on it... nothing hurts it.

are you Rustoleum guys using a primer?

I used Rustoleum and No primer just sanded everything.

I redid the areas I could get to on the 311 with gray Rustoleum. It was a little lighter than the original Formula bilge paint - no primer - went on and stayed on without an issue. I've used with hardener and without. When it dries, it is super tough - I don't think a hardener is needed.
