I second that. I have a black roll that seems to be bad. Everytime I try to peel it of even with a little heat applied, the painted glue backing likes to stay behind. I always acetone it off with a rag. It takes a bit of work, but it does come off.


When I recover a whole aircraft I usually just tear the old covering off, clean with acetone, sand and fill the balsa, wipe down with a clean white rag until I see no dirt- then recover.
This is the quick simple method I use without getting too much into detail.
