Re: PVC fabric source?
The air deck is under much higher pressure than the tubes of an inflatable. The tubes are designed to inflate to about 3.5 psi and the floor 10 psi.
I don't know how to do the math but I'm sure the floor psi goes up when 1-3 adults + gear are on top of it.
How will that pressure affect a glue repair? I'm not sure.
I do know that it is possible to order the air deck from most manufacturers.
Keep gas off the air deck, it will destroy it (don't ask). Mercury Marine also suggested (over the phone) that I keep the deck covered to protect it from UV.
