Not trying to thread jack or anything.
I'm not sure what he used for stripping the tank but Aircraft stripper is some good stuff, not the spray can tho, the quart can of jell you brush on. It will eat paint quick, and if you get it on you it burns like H#!!

Ok, Im through thread jacking.
Good start on the rebuild man! Waiting to see how it comes out, keep it up!
