I was amazed how much these were going for, the latest one in really good shape went to $470. The one bolt action one went for $525. To think that I used to scoff at these Mattel Plastic rifles. Even the clip magazine is going for $70. I would imagine a plastics supply house would have what you need to polish this plastic. I am sure it is a multi step process like it is for plexiglass. I will say though the Remmy Mohawk in .308 with that plastic stock was a good looking rifle with that rib and schnobble.
