It's just superficially damaged with a few score lines, as if someone raked a nail across it here and there.
Can anyone recommend a way to make it look slightly normal again. I was thinking of using a razor blade or something similar to carefully 'shave' off the raised burrs, but then what should I use to smooth it off ?
Maybe some wet & dry ?
I want to avoid paying through the nose for getting it replaced, so I've just one shot at doing it properly - assuming there is a way....
Any tips greatly appreciated.
