I first got this guitar about 7 years ago from a local shop who offered it to me at a discount for having a couple dings in the paint job. I didnt really show this guy much love over the years and I finally decided to refinish it. The plan was, once the paint was off, to see if it was a nice piece of wood worth giving a natural finish or if I should do something else. I got the top layer of paint and primer off and found a beautiful single piece of alder with great figuring (pics soon), but one small problem. It looks like there is a seriously thick (thumb nail size) sealer I assume before you get to the bare wood. I used a heat gun to get the poly finish off, but it seems to have very limited success busting through this stuff. TL DR Does anyone have any suggestions for getting super thick sealers (I think) off to expose the bare wood?
