Weird how all of a sudden there's posts about similar things at once. A google search turned up only one outfit around Los Angeles that cleans gas tanks, RUSTECO, and they want ---> $575! <--- to dip-clean a 20 gallon car gas tank. I could probably have a stainless tank fabricated for that much money. So I may have to attack it myself. I am thinking that if I can find a solvent that will dissolve that junk in there, I can then do a more ordinary clean/derust. Assuming I can find a solvent, I am thinking that suspending the tank with rope about 3 ft off the ground, putting 10lbs or so of pumice rock and solvent, and shaking it back and forth might do it. I can sit my lazy a** in a chair in the shade and shake it well. If I get the gunk out of there I'll use brick cleaner for the rust, thanks Frank for the tip! I can experiment with small chunks and a few teaspoons of solvent on the bench. $575 buys a lot of home experimentation! _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list
