Update:
I used 2000 grit wetsand, glass cleaner (windex), then sprayed 2 coats of red with 15-20 minutes in bewteen. Then cleaned the new red coats and applied 2 clear coats with the Krylon Fusion clear coat for plastics. I also masked off the signal lights with masking tape.
I'm very happy with the results! I still like the valenti leds but this will do until I can afford those (unless someone wants to buy these of me)
Here's a quick cell phone shot:
