I know that there have already been a couple of posts about this but I why not start another. I have a small amount of rust around the gas cap and in small areas in the tank. I have read all kinds of ways to get rid of it but since there is only a small amount of rust i don't really want to use any of the linings processes (Red-Kote, POR-15, etc). I was wondering what you guys out there are using. I was thinking about using some kind of acid wash but not sure what to use to make sure the inside doesn't begin to rust since it is etched metal. Let s hear what the best solution is!
