I have a AVRI 57 precision bass (which i love), but there's something about it that im not really a fan: the sticky nitro finish on the back of the neck. I read on some other threads that I could just use some green scotch brite on it to make it feel more like satin, but im kinda worried that it could damage the neck and reduce the life time of my bass, whats your thoughts about it? thanks
Well, the nitro finish feels sticky because of its high gloss. Basically, all the Scotchbrite will do is put a very fine scratch pattern into the surface that dulls the shine and reduces overall contact area with your skin; this is what makes the neck feel smoother and slicker. As long as you're not scrubbing it hard enough to actually get through the finish to bare wood, you should be fine. Just rub until the surface looks evenly dulled to your satisfaction.
Sticky is sticky. High gloss does not necessarily mean sticky. I've got a high gloss G&L neck that isn't sticky at all. I also have a much older one that does get sticky. To the point of the original question, try some nice high quality carnuba car wax. You don't need to abrade the finish.
I had the same problem with a Gibson SG "faded cherry" six string guitar that I bought used. The neck felt sticky, and no amount of cleaning would make it feel right. I thought the finish was defective, and I did some research on it, and I found that some peoples body chemistry is not compatible with nitrocellulose lacquer finishes. Thier perspiration actually dissolves the finish. I used these :http://www.rockler.com/product.cfm?page=17318&site=ROCKLER I started with the finest grit, and found it was too fine. I ended up using the coarsest grit, and it gave excellent results. I have since found these to be useful for taking deep scratches out of the finish on other instruments. The finest grit will give a mirror finish, and they have not shown any wear after a lot of use. Dip the pad in a tub of water as you use them to keep them from loading up, and keep them wet as you work.
Sometimes nitro just feels sticky. Dulling the finish will help some, but sooner or later the neck will regloss just from playing it.
