So I stopped in at a local mom&pop to grab a new polishing cloth for my new AV 58 Precision yesterday. After a small discussion about what's good or bad to use on nitro, I asked if the Planet Waves cloth he carried would be ok to use. His answer was yes. After playing last night I have the bass a little wipe down and then noticed hundreds of very fine scratches. They weren't just swirls, as there had already been some on the bass just from natural play wear, but scratches. They all followed the patten I used to wipe the bass down, some appear pretty deep. I'm not sure what to do about it. I know as a nitro instrument that its prone to more wear then poly, but now I've got some pretty nasty, unnatural looking marks all over the top o what was a brand new bass. How far should I go in pursuing a repair from the shop? I know that being knowledgable about what I can and can't do with my finish is my responsibility, but I trusted this guys word and wound up with a pretty marred top on my brand new bass. Should I bring it in and show him and ask for a repair or will it be futile as I have no real proof? It wasn't until after it happened that I read that microfiber can scratch nitro. Any thoughts?
