Modding Painting Plexiglass

I want to paint some plexiglass white for my htpc. I want to paint the plexi on the backside so when you look at it see through the clear part to the white. I was wondering what would be the best paint to use on plexiglass? And would regular spraypaint like duplicolor work because I'm on a tight budget.
Thanks

 

i think for plastics youre supposed to use vinyl dye

 

this was a few cotes of black engine enamel. I tested auto paint and it goes on too thin. For some reason regular old krylon looks the best. The benefit of using vinyl die I've found is that you can still glue on the side that you've painted over.

 

Thanks. And is it the normal application process?

 

I used Rustoleum Car Paint. I didn't sand or anything, but made sure it was clean. I did 1 nice coat and 2 if needed. It came out great. Just remember, don't prime it as you see the primer on the other side.
