I had a few moments tonight at work. I had my friend’s heat gun and I was very curious, so I dove in.
I went for it, and nothing happened… for about 30-45 seconds. Then a big bubble appeared. I stuck my flathead screwdriver under it and a huge piece of poly just lifted up. I kept going, and within 20 minutes it was all off. Holy shit! It was SUPER easy.
Edit: there was 239 grams / 0.527 lbs of finish on the guitar.
I’m extremely pleased so far.
