I use duracoat, its expensive, but works well. I made my own custom match, which started with their vz2000 color, added a few drops of bright blue, and cut about 60-40 with gloss clear. Was able to duplicate the factory finish to well within the variations of parts kit colors. The vz2000 is already a good color match for the greener end of the color range, but the few drops of blue, put it right in the middle of range. However, without the gloss clear mixed in, the sheen will be far too flat to look at all correct.
