No prob -- here's what you do...
First of all, does it show any wear? If so, follow those lines. Just as an artist would draw a hill in the direction that a hill would go, make the wear, where it would be -- but more so.
Also, copy some pics of vintage instruments. WHere are they worn out? Where are scratches likely to be. Some "relic" instruments scream of phoniness.
Use a medium sandpaper to take off a lot of finish and a fine steel wool to smooth it out.
You can also take a chain and just randomly bash a few spots. (Obviously, without pu's and knobs on).
ANd of course, only do this on a nitro finish. They're the only ones that tend to show that kind of wear. I've never seen a relic'd MUsicMan, unless it just abused -- and that ain;t a good look.
Go for it. If you mess up, well, that's what happened. Relicing is years of mess ups. There are no wrong dings.
Good luck.
