I read about several folks, I think on this board, that have had success with the Krylon Fusion? paint, its the paint specifically designed for plastics. Then, just use the camo paint of your choice. I remember they suggested lightly roughly the surface with some sand paper prior to painting. When it does scratch off, just touch it up. Yes, I agree, a cheap fix. I'm in the same boat, just got a Stevens 25-06, and wondering if I should do the paint thing. It may stay "grey" this season as I'm running out of time.
