Do a search on "hyperhidrosis" to see if your symptoms are typical to that condition. I had a friend and upstairs neighbor when I lived in NYC who had it and he frequently apologized for it when shaking hands or avoiding shaking hands. If you don't have that level of the condition, baby powder works. In my bass-playing days I had Fender Precision which had a gloss neck (70's model). I always kept a small baby powder in my case. If you have it bad, powder might not be right for guitar because it clumps against frets and requires a lot of maintenance or you'll get oxidation
