Okay, so my wonderful girlfriend just bought me a Warwick Thumb Bolt On 4 string off Ebay... (she's a keeper huh?) Anyways, I got it and it has some dings on it. Now I am very into taking care of my stuff and those dings bothered me very much. There was basically one at the bottom / back of the neck (where your palm and stuff slides across) near the second fret. Looked like it neck dove into the corner of a table or something. and what looked like a pen stab on the body in the front above the neck. there was one more near the input jack... So I went to Warwicks website and they mentioned how to get dings out. So I took the soldering iron like they said and a wet sock and put the sock up to the ding and proceeded to "steam the dings out" by pressing the soldering iron to the sock over the dinged aread... Now all the marks are barely noticable or non existant.... I had to steel wool the neck ding but not it is basically even, cant feel it. The dings become only noticable when you point them out. Very safe way to bring your natural wood basses back up to the first day you got them. All i can say is THIS WORKS!
