For masking clear canopies I use a tape from a company called: NICHIBAN.
It is really thin(I think it is made from rice paper), easy to cut with a keen blade, and most important…it doesn’t leave any residue even when left on the canopy for long periods. A little goes a long way, and I bought the rolls that I am using many years ago…so I cannot tell you where you can get it. But I think I must have gotten it at Micro Mark.
Hope that helps…good luck.
hmmmm that sounds interesting enough to look for… I’ll try anything once!
How well does the tape-burnish then remove technique work for removing the residue from BMF? I am still looking for a good way to remove it from the plastic.
Although I usually use parafilm now, for years I just brushed on a couple of coats of ordinary white glue (Elmers), made more brushable with just a drop of dishwashing liquid and a little water. I’d clean up the edges before hand and cut the paint afterwards with a sharp blade. There was never any residue even if left on for a long time. I didn’t Future the canopy until after painting and removal of the mask. It was a lot quicker than parafilm but didn’t have quite as sharp an edge.
