Good Evening Looking for ideas on how to clean a fuel tank? It dosent leak . Just has some surface rust and corrision in it from sitting so long. So it dosent needs sealer dumped in it. but most of the sealer kits call for a Muric acid rinse prior to sealer. Anyones thoughts on just using the acid and not sealer to clean the tank? Oh I also did a air pressure test for leaks and its solid. Thanks Kilroy was here!!!
