I've seen the guys at FoxyWoods do some spot (and complete) re-finishes on a few guitars. They found a company (I forgot the details) that'll mix (paint wise) pretty much anything they need, not cheap at all - but damn useful.
I recall the Martin repair and 63' strat re-finish both came out quite sweeeeet.
