Curious, were the tanks QB? I have a few approaching this size, mine were QB's. Looks like a winter redo project for you too

I had one like that on the upper outboard corner of the tank. Nowhere near a rivet. Weird. Anyway, I pricked it with the point of a razor blade to let the air/gas out and now it sits flat and seems to have re-adhered to the skin and is not noticeable at all. Really weird. Standard build tanks BTW.
