Thanks all,
JJ - Good to know. *I thought that might be the case, Concept being a
catalyzed paint, but my worry is based on way too many years of using
non-catalyzed paints.
JS, Yeah, that was quick, but really scary. *There was no evidence of
an S seal ever being installed, just mylars top and bottom. Believe
me, I will be very happy to finish this round of refinishing. *I'm
going to celebrate by growing fingerprints again, since I've worn mine
off. Next year the tips and horizontal, and maybe the fuse in 2014.
Bob... uh...thanks?

Hi folks,

My question is at the other end of the seal's lifespan - how to remove
the tape adhesive residue from the wing once the Mylar seal has been
removed? My progress, mechanically, is about 300mm per hour and I
would really welcome some practical advice on how do this more quickly
and less painfully. Recommendations on chemical solvents or
proprietary products would be appreciated. The aircraft is a PIK 20B
superbly refinished with 2-pack polyurethane about 9 years ago.

It very much depends on the adhesive used.
I keep on hand acetone, laquer thinner, and 3M General purpose adhesive cleaner that is commonly used for automotive trim.
Add to this a very sharp chisel and a variety of scrapers.
Then, see what works with your particlar application.
You won't disolve the adhesive, but hopefully will find something that stops it from wadding up in a stick nasty wad.
It may take 2-4 passes to get really clean.
Good Luck
