I used badger film Frisket.... I had some problems with it..... The glue can disolve into the paints.... And it can pull paint.
What I think that means is if the paint is fresh, and any one painting is likely to use freash paint, that solvents in the drying paint attack the frisket glue..... So these traped vapors then react with the glue and the paint it is trying to leave....
It can leave blotches that can be sanded out, providing you can sand that layer of paint....
The glue that remains can be removed with common rubbing alcohol... I called them as the glue turned to yer basic spider web...
They also said you can remove the paper for 30 minutes to let the film dry, so it won't stick so hard......Mac I know this is old, but maybe some will save a lot of hard work...
