Hi! My TBA is doing fine but my girlfriend's Honda Nighthawk has a small pinhole in the side of the tank. It looks like the paint chipped and rust took over. Any tips on repairing? I'm thinking to draining the tank, take it off, clean it out very well, and let it dry for a month or two before doing anything. I thought I heard somewhere to fill up the tank with CO2 from a fire extinguisher and then braze it or weld with a wire-feed welder. Does this sound right?
