Teflon gap seal tape...

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?

When JJ and Udo agree on something it must be true 8^)

Here is what I was thinking, and I am prepared to be proven completely
wrong. First, Mylar seals (combined with anti-peel tape) appear to be
thicker than Teflon tape, so unless I'm willing to go to the trouble of
routing a groove to inset the Mylar (which I'm not), the Mylar would
seem to me to be every bit as likely to trip the airflow as the Teflon
tape. Second, the point behind external tape (or internal seals) is to
prevent airflow through the gap. Are properly fitted Mylar seals
actually going to prevent this flow? Would it make sense to use Teflon
tape to seal the gap, then put Mylar over the tape?

Thanks,
Marc
