transfer/ doublesdied tape.

Mylar seals continue to come loose from my PIK.
Some have been there for some years and leave a yellowish residue of dried
adhesive which can be easily scraped off as a powder;other sections have the carrying film left behind and a sticky adhesive layer on the wing; this needs solvent for removal.
At least two types of double sided tape have been used; one from W and W
came with a roll of mylar; the other source was a stationary supply store
product. Recently I found a dispenser of double sided film trade mark "Studio".
This is el cheapo and not to be trusted.

Any good brand experiences with double sided adhesive film?
It is always the mylar face which lets go.

I have till Sat to make a choice when replacing three lost sections.

cheers
