I'm looking for some responses on my idea of adding a slight glossy finish to my 60's SG Tribute. The guitar is a great player but it has one of the "unfinished" nitro finishes that Gibson was producing awhile back. I was watching a video on applying a finish of Tru-Oil on a rifle stock and I noticed that people were doing the same on guitars as well with good results. My question is whether or not it would interact with the nitro finish in any way. I would try it in a small spot first, but was wondering if anyone else has tried this. My SG is below.
