After years of building models, I have discovered a way to cover surfaces without CA adhering to a surface. I first tried plastic and it was glued to test piece. I then used waxed paper adding a extra coating of wax. It helped, but some areas stuck. I then used the plastic undercover of TopFlite covering. It did not stick. I retested and it worked perfect. So all these years a simple discovery of throw away undercover has helped me to build without scraping and sanding to get the stuck paper off the wood and blue print surfaces.
