Don, I never tried the plastic wrap or the other covering materials. I have never been able to successfully wrapped a sandwich with the wrap without it all getting stuck together and making a mess. I never used the iron on shrink stuff for the R/C planes either. I bought 1 roll of the bright red for a plane I was working on but I don't remember ever using it. It's still on one of the shelves in the loft. Bought the teflon coated iron too. Never used it either. Guess I was just stuck on the old ways.
I've got a couple of Sterlings Peanut Scale planes. Maybe I'll try to build one of them and use the Saranwrap to see how it goes. I've still got many different colored sheets of the tissue too if that doesn't work.
Jim
Stay Safe.
PS - Don't have any planes to repair at the present time for the museum so I might get something done.
