We shippped a set of tanks to a customer that was coated by POR .
When the customer received it, the coating had flaked off.

Yep, some years ago ,about my daddy decided that the old 1000 gal gas
tank setting out back would be better as a 400/600 diesel/gas tank. He
got it cut about half way around whe we were exposed to a VERY
impressive flame from the tank. The tank had set empty about 4 or 5
years. I have soldered gas tanks but would never consider welding a gas
tank (don't have the know how or correct toys).

When I used to braze cracks on Harley gas tanks, I just stuck an air
hose in the filler opening and let air blow through there at low psi.
Never had a pop.
