FYI there are two bike painters with "Spectrum" in the name, and I'm sure they don't want to be confused with each other.
The first is Spectrum Powder Works (www.spectrumpowderworks.com)
The second is Spectrum Cycles (www.spectrum-cycles.com). Spectrum Cycles of course builds excellent frames in addition to doing excellent resprays. Tom Kellogg did my Jack Taylor that you can see here: http://pg.photos.yahoo.com/
While I don't know anything about Spectrum Powder Works, I can say that Tom Kellogg did a fantastic job on my JT. But I don't think he does powder coating ;-)
