Specialty Tape Question

I am looking for a source for a special kind of tape that I saw used
on another glider. I don't know the generic name, but this tape is
applied somewhat permanently to both surfaces that will receive normal
gap sealing tape. I'll call it "anti-damage tape". The stuff I saw
was 1/4" wide, very thin, and was *very* sticky on one side and had a
high-gloss very smooth white surface on the outside. Its purpose is
to supply surfaces to which normal 1/2" gap tape will easily adhere.
But when removing the gap tape during disassembly the gap tape pulls
off the anti-damage tape without pulling the anti-damage tape with it
(implication is the anti-damage tape adheres much more strongly to the
glider than the gap tape adheres to the anti-damage tape). The anti-
damage tape will remain firmly stuck to the glider surfaces (e.g.,
wing root and mating fuselage surfaces). The net effect being
absolutely *no* paint or gelcoat is pulled off of the glider itself
when removing the gap tape.

Hopefully the above description is clear. Any ideas for a source
would be appreciated.
