gas tank
the tank i'm working on is two cylinders, which will be strapped to the frame with leather belts for an old-time motorcycle look. my initial thought was to use pvc and paint it silver, and although i found conflicting opinions on whether gas would eat it away, the most reliable source indicated that the pvc itself can withstand gasoline, but the cement might dissolve. my plan was to use liquid gas tank liner to prevent that problem. however, when i went to home depot, they didn't have pvc in the 4" diameter i wanted, so i went with abs, which will definitely dissolve in the presence of gasoline. my new plan is to use fiberglass resin to coat the inside first, and then after it is cured, use liquid gas tank liner to add a second barrier to the gasoline. it may well fail, but i'm going to give it a shot anyway. i'll post pics of everything when i'm done.
