On gas tanks that are too caked up to clean by tumbling and are way beyond being boiled clean by a radiator shop I usually cut an access hole in the top and sandblast the crud/rust out and then take them to the radiator shop for cooking and sealing. The access hole is patched back in first. The problem with the blasting is you can get the sides and bottom very well but on a shallow tank you can't bend the hose and nozzle around to get the underside of the top and it's usually the worst. You know how when pressure washing an engine with uneven surfaces the water will get blown back in your face? Used this idea only with sand by putting a brake backing plate with all it's dips and bends inside the tank and then blasted it which ricochetted the sand every direction and cleaned the blind underside of the top. Guess even a blind hog finds the acorn once in awhile. Oh yeah, all the trouble because it's for a 1941 International Harvester 1/2T K series pickup---not found easily.
Necessity is the mother of all invention... Glad your improvised reflector worked for you, Evan! Damon
