I use this to lubricate the saddles, nut and string trees on my Charvel DK24 HSH 2PT, which has a floating Gotoh 510 bridge. This stuff is great. When doing hard bends, my G and B strings would always be a little bit sharp, but not anymore with this. Tuning stability is amazing now, especially for a non-locking floating bridge.
They use it in the Fender custom shop, so it can't be that bad, can it.
