In a recent e-mail conversation with Ray over at Ninja I learned that the outer coating on these tanks is a gel coat similar to a boat. It can crack and craze but this does NOT cause a tank to fail inspection and it CAN be reworked with a new gel coat for a fee to make it look good again and to protect the underlying fiber wrapping.
Just as a reminder, Pyramyd Air sells life extended cylinders too. https://www.pyramydair.com/life-extended-carbon-fiber-tanksThanks,Taso
It's nuts, I know. UPS and FedEx are roughly the same in terms of shipping. I checked AGD and the shipping for one tin of pellets was something like 68 bucks. I don't have a lot of folks in the states, so I just try to work with what I got. There were several members here who stepped up beautifully, though. They didn't know me from Adam but they offered to send stuff out to me. I am so grateful to each one of them, bless their hearts. paul
