I see that PRS is using a nitro finish on all guitars as of 2020, so my incoming S2 McCarty Thinline will have that finish. I know that PRS recommends a quality furniture polish, not guitar polish for nitro - but what about cleaning before the polish? Will the PRS cleaner be OK? Anything to avoid? I've read somewhere that necks finished with nitro can get sticky. Any of you experienced this? If so, any fix?
