Don't forget to sand the chassis edges, battery slots and tape slots and then CA all the edges. I use Emery cloth and put the chassis in a vice grip with rubber mounts as not to damage the chassis. I use a long strip of emery or like 400 grit paper with the chassis in the vice and just go back and forth to get nice smooth finish. Works great with the vice holding the chassis. The outside edges I use the CA and put on a heavy bead and just move the chassis around and let the CA run around the edge.
