Re: Need advice on cleaning out my gas tank

Leaving it uncoated is not really an option as it will rust so fast it will make your head spin. The coatings work just fine and I have had them in various tanks for years.

Lately I just let my local radiator man do them for me. He has a wonderful process for tanks that have a lot of accumulated varnish in them. It is almost impossible to wash out a large deposit with thinners. He has the tanks baked at high temperature at a heat treating facility. The varnish turns to something like charcoal which he can then remove. I took him a 48 Stude tank with something like an inch of varnish goo on the bottom. Afterwards he gave me back a cardboard box full of the residue. After baking he has to resolder any connections that melted loose and then recoats the tank inside and out. It makes a beautiful and very sound job.
