Not sure that tape is the way to go, Mark. I have found that properly
installed Mylas is all that is necessary. Proof--------when the seals
on my Nimbus 3 needed replacing, I eliminated the internal seals and
also got rid of that ridiculous lower mylar that went inside the gap,
never did understand the reasoning there. Replaced it with Mylar on top
and bottom, nothing else. She climbed and cruised right with another
Nimbus 3 with factory seals.
Another data point..............The ASW-20 had a terrible reputation
for dropping a wing and entering a spin, when they first came
out.................then the spin problem seemed to go away, why? Most
20's today have Mylar, top & bottom. Was the external tape triggering
separation at low speed?

Something to think about,
JJ
