Properly refinishing a guitar can be a lot of work and require some equipment to do it right...a compressor, a spray gun, and a buffing wheel. Below are the basic steps for a sunburst or transparent finish as I posted once before:
As far as refinishing, just about everything you need is available at Stewart McDonalds Guitar Shop Supply (
stew-mac.com). Correctly refinish a guitar, especially sunburst can be a big undertaking. Basic steps are:
1) strip finish via sanding...try not to ever use chemical sovents if possible
2) fill in any gouges with either grain filler (if really tiny) or wood putty
3) level with sanding block up to 320 grit
4) optional spray with sanding sealer and level again
5) spray with transparent yellow
6) optional thin spray of clear laquer
7) airbrush (from outside in) your transparent blend tone
8) optinal thin spray of clear laquer
9) airbrush (from outside in) your edge color (sometimes a transparent tone, sometimes an opaque black)
10) 2-4 (depending on how many clear coats are on it) layers of clear coat
11) sit for 3 days and level to 400 grit
12) 3-4 layers of clear coat (usually aim for a total or 6-8 layers or clear coat...too thin and you will have hardly anything on the guitar by the time you level it, too thick and you can get finish cracking problems later)
13) sit for a week and level to either 1200 or 1500 grit
15) polish with a good guitar polish
for a solid color, substitute the following for steps 5-9:
5) spray a overing with a sandable laquer primer (usually an automotive primer will do)
6) spray two coats of a colored laquer (usually automotive laquer will do...just make sure it is laquer and not enamel!)
skip steps 7-9, start above with step 10
Dan Erlewine's book on guitar repair has a very good section on doing all of this. In fact, I believe he is in charge of the technical department at Stewart McDonald's.
