GE Novalux

My latest signal was delivered Friday, I'm gonna need some help and advice from you all restoring this one.
The red lens is cracked, and the green lens is a (blue version) Darley, I'll be looking to trade that one for a spider if anyone is interested. Over all it is in pretty good shape, except for a couple holes that were drilled in the back for a three way thumb switch, and ground wire.
The reflectors are in fair/good shape, with a few cracks on the outer edge on two of them. The lenses and reflectors were cleaned up a little before I took the pictures. I'll be bringing this to OSM, so you all can give me some tips on the best way to get this signal cleaned up and ready for paint/powder coat.
Here's some pic's.
