As far as fretboards go, I buy bare necks with fretboard and frets installed, then shape the headstocks and apply finishes. I buy blank boards for the bodies and cut & shape them with a bandsaw, a router and sandpapers.
My finishes are always done in nitrocellulose lacquer with a small compressor and a spray gun. Getting a good finish on a guitar is the same as a good paint job on a car- it's all in the prep. Grain filler, sanding sealer, and multiple grades of sanding until the body is really smooth, then color coats, many clear coats, and weeks letting the lacquer cure & harden. Next is wet sanding in progressively finer grades up to 4000, then polishing with automotive polishes; I use Meguiar's products.
