Hey guys I got a quick question for yall. My bull was from new york and thusly the underbody is pretty rusty. ive started to rust fix and paint the underbody but i noticed something on the gas tank. the gas tank on only two corners has rust. its not rusted through and it appears to only be surface rust right now. Whats weird is that the bottom of the tank has like no rust on it. how? so how long do you guys think i have? what should i do? i dont smell any gas fumes and have not leaked any gas. Is it unsafe to have rust on the gas tank?
