Everyone says they cant do it cause the longevity isn't as good as glass. I've tinted a spare soft top window and left it in the sun for two weeks. Folded the window, roughed it up, done everything I could to make it mess up and I couldnt. It was dirty because it was an old window but no bubbles or peeling. I even put some tint strip on it and stripped it off like a regular glass window and it came off perfectly fine.
