Anyway around this? I used some plastic polish that I use on the headlights of my cars, but there is a deep scratch in a few of the holders that I can't remove. It's really driving me nuts and I tried moving the lighting around everywhere to get the scratch to 'disappear', but no luck.

What do you guys use for plastic polish? You can see the scratch at roughly between 9-10 O'Clock on the obverse of this dime, as one example. It really shows in the full size version.
