Depends on how much after-the-spray cleanup you want to do. Spent 1/2 a day taping windows, lights etc. It does peel off, but it is still labor to remove it. Spent about 3-4 hours spraying. Was world rally blue to start. Used one gallon of white base, probably should have used two gallons . Used 1 gallon and a half of the green. It has faded...........but still have gal.& 1/2 to respray. Inside curves will pull when it dries so don't lay it on too thick, too quick. Plenty of online videos from Fonzy at dipyourcar.com
