Guys,
I cannot get a fuel tank sealer kit in time to do what I need to accomplish -- this weekend.
I have an old 8HP upright Briggs with the square 1-gallon tank affixed with "saddle straps". The interior of the tank is rusted to the point where pebble-chain-roofing nail treatments won't get enough of the rust out to prevent clogging the filter ASAP.
I can acid-etch the tank OK. I have hydrochloric, hydrofluoric, citric, and phosphoric acids available. I can sandblast it, too. But I expect after an acid etch, I'll probably have some pinholes.
So here's the question -- Is there anything really special about the epoxies used to seal old tanks? I have a solvent-free two-part material normally used for "clear-coat" applications on wood. It's a true epoxy, not an acrylic or a polyester.
Should this stuff work OK for gasoline contact? I work with chemistry a lot, but have little experience with solvent-resistant coatings.
