We just painted one of those pumps. We didnt keep the motor to reduce the weight. As far as frame, we sandblasted it, hit it with epoxy (etching primer), and lastly coated it in silver rustoleum (sprayed on, not rattle can). Sometimes I use flat black urethane.

Anyway, pretty simple, but works. I have an MS80 that we did same way that is just a painted frame still. I'll add a pic to this post later when I get a chance.

Steve, that pump is awesome!
