I could try to polish it with some compound, I have read that maybe toothpaste could work but I am afraid to try and make it worse
and that is why I am asking for info and advice from someone who has tried this before with good results.[/QUOTE]
I have had good results removing scratches from some older MacBooks with metal polish like Wenol. It does diminish the gloss, and won't remove deep gashes--but it polishes out most of the small scratches.
Also, there's a guy at MacBookAdapters.com who refurbishes them nicely and sells them with new, stronger cables and a smooth--but not glossy--finish. His prices are reasonable and he seems like a nice fellow. Send him an email--he may reveal his refinishing process to you.
