Sry.. Not an Electric.

Back story..

Got this thing more than 15 years ago. Pricey for me at the time, but I didn't play it a lot as I always concentrated mostly on Electric wankery.. Annnnd I fucked it up.. I kept it in the Case to long while putting Humidifiers in the Case without knowing what the hell I was doing. What happened is the Finish got cloudy. Moisture gets trapped under the Finish and it's over. I don't think it altered the Tone, but it kills me that it looks like pure shit from when I first got it.. This only affected the Back and Sides. The Top is fine.

This Guitar is twice the price now, and the new productions aren't as good. I gotta fix it. I'm up for the challenge. I'll just do the Body and leave the Neck alone. The Top has Nitro and the Back and Sides are Polyurethane, and that shit is HARD.. I started sanding by hand with 220 Grit Thin Sanding Sponges which are awesome, but it was taking Forever to get thru.. I had some Paper 100 grit and hit it with that and started to get it down.. I ordered some 120 Grit Sponges, so I'm on hold until latter today delivery..

I plan to wet sand the Nitro off the Top with 400 grit down to the Sealer and I'll do the whole thing with 2K Poly going thinner on the Top.. I think it will be fine.. Nitro is a fuckin pain and it keeps shrinking.. I want a Catalyzed Finish the cures right now and not in a month before I know I need to do touch ups or whatever, turning this Project into a 3 month Anchor..

These pics are in focus, which really shows how bad it looks..

I think you should have tried Xylene before sanding and it would have taken that out in seconds. It'll re-emulsify most finishes that aren't water based.

Have to work fast and light or it'll melt the bindings/plastic but I've used that chemical to fix a lot of different finishes.
