I wonder if I can use it for fret polishing as I do with steel wool sometimes. My current method is P600-5000 grit sandpaper but sometime I use steel wool before, and I'm finishing it with metal polish cream. It gets really smooth, I have to work at least 15 minutes per fret but for me it worth it.
BTW I used the 7448 earlier for leveling the finish and it works great, glad I heard your advice.
When do you use the 7447?
