use some cooking oil!
They helped my fried egg from sticking to the pan earlier on!
Just use the Dunlop guitar polish on the neck every time it gets sticky.
It'll be silky smooth.
My guitar necks don't get sticky on their own, so I suspect it has something
to do with our moist palms or something..
i've taken very fine 2000 grit sandpaper and very lightly wet-sanded the back of my '74 SG before...no harm done but of cos plays smoother.
im not the first and i definitely wont be the last person to keep doing this on gibson necks...
its the best solution compared to everything else out there...lubricants or whatever crap.
