Latex is not fuel proof and must be clear coated. The nice thing about latex paint is the paint matching systems they use to make your paint the color and shade that you might need to match an existing color. I can take a color swatch down to my local Home Depot and they make me a color match that has yet to miss. I even got some white mixed up to paint a cowl that I needed to color match my covering. With a million different shades of white available, the match was perfect. You need to let the Latex dry for about 2 weeks and then clear coat it. I am sold on latex paint completly. You can do a search in the RCU forums about rattle can paints and find out if they are fuel proof, some are and some are not. Good Luck, Dave
