I'm about to sand my guitar body back to bare wood for the second time.
First time I thought I'd try a new finish that a guitar builder liked a lot. Unfortunately it burned through with incredibly ease (maybe I wasn't supposed to level sand it?)
So sand back, restain and decided to try Crystalac, because all these builders are crowing about how great it is.
I used six coats (three a day, four hours apart) and let it cure for a week (a day a coat they say).
Well, I hand sand and I use a 5 inch round pad (soft) that's about a half inch thick to hold the paper. I started with 800 grit.
And the weirdest thing happened - it burned through ALL the way around the face and back, but not on the rounded edge, nope, about 1/8th of an inch before the edge. Like there was hardly any finish there (there was some orange peel there, so not like I could ignore it). The curve for the edge? That's fine. I level sanded it out of curiosity and it didn't burn through at all.
Glad I only bought a pint of this stuff! Hate to be throwing out a quart at the prices they charge.
So I guess I'm going back to General Finishes gloss. But honestly? I don't get it. It didn't burn through on the edge, it burned through just before the edge. I've never seen that before. Like all of the finish pulled away there.
Anyone seen that before?
