Refinishing a refinished guitar?

If you only sand the paint, you wont change the body contours. You would have to be pretty heavy handed with the sander to do that! I had no problem whatsoever with the sander approch.
Ive heard that Nitromores damages the wood, and will cause problems later in the guitars life.

Refinishing a refinished guitar?

Each to his own Mr Pig and yes, if you're careful and only sand off the paint, there is little problem, just seems the risk is a little high to me unless it is absolutely necessary and you know what you are doing. Sort of sledgehammer to crack a nut from my own personal viewpoint.  I've seen a number of guitars, particularly SGs with their sharp edges and Firebirds with the raised centre section, which to put it mildly have not benefited from previous sanding efforts. The impression I get from a couple of expert forums is that luthiers generally tend not to favour the sanding approach unless nothing else works.

Incidentally, I have absolutely no reason to believe Nitromors damages wood, nor have I seen any damage from personal experience over a number of years and many, many, guitars and different woods. I can't imagine any chemical reason why the wood would suffer either. I do make sure that all remnants are cleaned off, but you would (or should!) do that anyway before refinishing.
Just 'cos you're paranoid doesn't mean they're not out to get you

From memory theres also two versions of Nitromors, which is also used in the printing industry to remove ink from equipment.

The regular stuff you wash off / deactivate with water and the other one you use meths to remove it.

Possibly the latter one may be slightly better option to keep the wood happier (though I used the water based one on my old SG years ago with no ill effects), Though my nephew knocking it over 6 weeks after the refinish left a huge dent that I never fixed.

Some of the nitromores stories come from the companies who where into the dip & strip, who actually just used caustic soda. This caused real serious damage to the wood, including seriously raised grain.

Cabinet scr@pers are brilliant for getting a nice finish (my father made some real fine ones that where amazing for smoothing the primer).
