though not likely his wing - this is likely the type of failure experienced....

Yes, that is the type of cut. I explained in post #5 how I think it happened. Definitely not pinched between plate and tank.

First, did you use Cotol-240 because aqua seal takes longer to cure?
Second, back in the day wreck divers (maybe cavers too) did use inner tubes to add puncture resistance to their wings. I am not sure exactly how it was done. But got the impression the bladder was removed and used as a template to try to fit the tube to the bladder. The cutouts for the dumps it would assume would keep the tube more or less in place.
No, I did not use Cotol. The Aquaseal directions say it takes 8 - 12 hours to cure without Cotol. 2 hours, I think, with Cotol. I patched and let it sit over 16 hours before inflating to test.
Your description of how people attempted to protect their wings sounds pretty much like what I was thinking. The thing I wonder is, it seems like that would be effective. And if the cuts I got are THE most common damage to a wing, why don't the manufacturers do something like that in the first place? Maybe it's just THAT uncommon that it's not worth it for the OEM to go to that extra effort?
