I bought a Pearl Flip on craigslist today for $100. It's in great working order, but cosmetically its quite scratched up. Would putting best skins ever on it hide the scratches or will it amplify them?

I don't think it would do much of either. There is a fluid out there for hiding scratches on screens. That would work

I have put BSE's on scratched up devices before and it does cover most of them up. If there is a deep gouge, then the skin will mold to that. But, in general, it does make your device look "shiny" again while covering minor scratches.

it should help but you also may want to check out getting Displex display polish
