I stumbled across this site, and the technology looks very similar to anodizing/plating. Does anyone here use this? How difficult would it be to build an electropolishing kit, Caswell?
Edit: I just saw their estimated prices. 6 Gallon tank = ~$6000 US. OUCH! Maybe that's why I sand/buff all my parts.
