Ok, in the spirit of trying to spark some activity on this forum, I thought I would share my latest endeavor. I affectionately call it Project Shine.

I decided to go with the sanding route instead of painting. They are buffing up nice, but what a bitch. The layer of epoxy paint on the bottom has to be sanded with 150 grit. The previous owner just globbed it on. The rest I start with 320 and work my way up to 1200, then rubbing compound. I have to constantly wet the paper, wipe the hulls, and wet the hulls. It's working though. Pete

Peter, when I first cleaned up my 5.7 I ran into the same problem of the removed material etting in the way.
I solved it by using a random orbit sander (with appropriate grades of paper), & a hose set on "trickle". If the surface you are working on has a good slope, the trickle of water carries away all the oxidized material, & the paper stays clean until worn out. Make sure you are plugged into a GFI outlet, wear rubber boats & gloves
