Got a question, I'm using some sheet plastic for my new building. As near as I can find out, it's made from a mix of recycled Polyethylene and Polypropylene. It is thin, (.05"), soft, cuts easily, has a rough texture but doesn't adhere paint very well. It resists sanding too, (100 grit belt sander barely takes the texture off one side). It can be painted, but scratches and flakes off if you're not careful. I've been using acrylics. I like it for my building because, it cuts easily and the texture resembles stucco in N scale.
Has anyone used this stuff and painted it? If so, does a primer work, or do I need to use an oil-based paint or even a rattle can? I would not think a clear coat would help since the problem is one of adhesion. I like acrylics because I can mix my colors. I've already used this plastic for my backdrop, a scratch or flake isn't as big a deal on a 36" x 36" painting as it is on an N scale structure.
