The neck on my guitar is great, but it's a little hard to move around on. What can I do to make the back of the neck smoother, and easier to slide up and down on? Good products (if any) you'd recommend?

btw, the neck is clear-coated to a natural gloss

I use Fast Fret on My Dean.It has a finished neck and I rub Fast Fret on the strings and on the back of the neck.I then use a piece of an old T shirt to wipe off the excess.Makes the neck and fret board slick and easy to play on.
