i painted my old yota in Sherwin Williams marine industrial paint. You can pick any color from their wall card things, pick flat, semi gloss or gloss, and they mix it up. It's thick paint too. Put it on via a pneumaic gun, and it coated heavy and thick... I was happy with it
I painted mine with machine paint from Pittsburg Paints. Chemical resistant, can use carb clean to wipe it down, ultra durable and can be mixed any color you can think of, except metallics. Use an automotive sprayer to apply.
