The last couple of weeks have been "SGI Recovery" time. I've been working on a Octane, Indigos, and and Indy.

My question comes up since all of these have a dark plastic for their cases - blue in the case of the Indigos and green for the Octane. On these dark plastics, scratches and scuffs are light colored, as the surface of the plastic is abraded/deformed.

What is the best way to minimize the discoloration of these? It seems perhaps a combination of light abrasion and maybe some heat would do the trick, but that could also make the overall scuff more obvious since there's texture to the plastic. I'm curious if careful use of a light abrasive like toothpaste or very light Magic Eraser might do the trick. Likewise, are there any "conditioners" that might at least tone down the scratch?

Willing to experiment on an Indigo case that's very much the worse for wear if anyone has ideas to share!

I've had good luck using magic erasers on Mac cases for scuff marks, as long as you don't go crazy with it there won't be any affect on the plastic's texture.
