4 (or more) hours of labor, two cans of caustic paint stripper, two plastic scrapers, half a dozen pairs of rubber gloves, various steel wool and sos pads, 4 different grades of emery paper, rubbing compound and finally Mothers Aluminum Polish brought forth the birth of a somewhat presentable aluminum one gallon fuel tank.
Now the next challenge if hunting down a proper fuel cap. First I'll try the IBMWR list and if that doesn't work I'll have to do some scrounging. Last resort will be having a machine shop fabricate one from billet. ($$$$)
