The best I've ever indulged my guitar to care !!!

This product is the Hammer said in advance! Unfortunately, I had lately little time for my guitar and it was dusty in the attic. The neck was really dirty and the wood had seen better days. After watching the neck with a card (ec, credit card, whatever) had freed from coarse dirt, I've applied this means. Now when I go through the neck it is as if the guitar comes fresh from the factory. The neck is really smooth and already you can feel no unevenness more. This product I recommend no ifs and buts !!!!
