I'm interested as well. Hoping to find out how to clear coat parts for the "black laquer" finish like the PSPEC shift knob. I know the knob is powder coated and polished, so I won't be able to do the same to plastic pieces...
xluben, I know that clear acrylic enamel will stick to bare metal, though not sure what it would feel like. If you did enought coats, you could wet sand it and polish it, but I'd be concerned about getting a 'sticky' feeling, or scratches.
