I got a stay-down license plate holder and primed and painted it. Gassed up a few days later, a couple drops got on it and went through the paint like shit through a goose. I don't recall the paint I used, was at a friends at the time, I'm thinking it was engine enamel, but I honestly wasn't paying attention - it was black. Anyhoo, what paint will hold up to the occasional gas drip?
