actually i did find a tag on the inside of the tank. a little bit bigger then an index card. stick to the inside of the tank. it oil soaked so i cant make out what it says. i have is saved and to the side until i figure out what i can do with it. i don't want to wet it cause i don't want it to fall apart. what would be a quick way to get all of this thick paint off? paint remover? its so thick that i want to remove some before i sand blast. thinking of maybe just burning it off?
