Is it possible to gloss over scuffs or light scratches on shrink wrap? I bought my first sealed game, and it came with some dried food stains on it, and some scuffs in an obvious place. I got the food off safely, but is it possible to "clean" scuffs or light scratches? Thanks, I'm relatively new to sealed games, and wanted to vga this, but if the scratches are permanent, I'm not so sure...
