I did a little experiment on my old F512R, so you know I was careful...a little unsented talc powder on a soft microfiber cloth, to see if it would take out those almost invisible scratches...well it did, used dry...Talc is softer than almost anything, not abrasive, yet on the black pickguard...smoothed right out....so I used it on the top edge of the guitar top, same, won't take out finish cracks of course, but did lighten up some pick scratched that someone left behind....careful who you let play.....So if you put a little talc in the crotch of your hand between the thumb and finger, you will probably reduce the friction a lot, and you could try the polishing bit on a small area of the neck or haze... and keep everytning dry is my suggestion....for what its worth....Steffan
