Non-S&W - Plastic Grip Cap

[MR .44 Spl]

I've got a Marlin 57M that I'm trying to get back in shape. After cleaning it up, and rubbing a few coats of boiled linseed oil on the stock, I've got it looking pretty good. One area that needs some help is the plastic grip cap. It's got some pretty significant scuffs and scratches on it. What can I do to buff the scratches and scuffs out?

Kit car polish will get out all but the worst looking scratches.
