I still think that this is your real problem - "If you have to slide your finger under the mylar to get it off, you may have a problem". Not the vacuum, not the foam. I told you at the very beginning of this quest that you are probably damaging the wing when you remove the mylars. You are sliding your fingers under the mylar with your nails towards the wing and you run your nails on the surface of the wing, correct? This is not a problem with heavy skin, but is a no-no with a very light wing skin. Regards, Oleg. RCSE-List facilities provided by Model Airplane News.
