Years back when I started polishing frets I had a dremal I used for other stuff and an assortment of attachments. Fumbling through them one day I found red polish compound and gave it try on frets and wow. Point here is if you have a dremal you may have what you need without buying something else. Since then they came out with those metal fret protecters so now I don’t tape off the fretboard.I have a guitar that needs a fret polish. Is it as easy as buying a set of fret erasers, taping off the fretboard and pickups, and 'Erasing' the fret(s)? Or is there more to it?
