Hey there! I have some PlayStation's CDs here that has few scratches. I'd like to remove them, so the CD will appear like new and work better. So I heard about "resurfacing CDs". I ask:
1 - What is it?
2 - Is it safe?
3 - Does it really removes the scratches?
4 - The CD will work normally?
5 - The CD will look thinner?
6 - Do you recommend?

Thanks!
