Is it safe to use Planet Waves "Restore" or Dunlop Formula 65 on Nitro Finish Guitars?
Dunlop's FAQs does say this though:
Q: Is the Formula 65 okay to use on a nitro finish?
A: Yes, Formula 65 polish is ok to use on a nitro finish. I would not use it if there are cracks, weather checking, or dings in the finish. I would not use it on an old and thin finish either. Rubbing on a thin and old nitro finish with any liquid polish and a cloth can take off color.
I wonder though how old is old? Are they referring to vintage instruments from the 50's and 60's?
I'm also curious if some of you actually use it for your nitro finish guitars. And hear about what you use instead.
