I have a gloss natural finish guitar, but over the last year, it has gotten many, many scratches. What is the best way to get rid of these annoying scratches? (especially if you are trying to sell the guitar)
Try Dunlop's Carnauba Wax. Just keep applying it and it'll eventually fill in finish scratches.
