I've done a lot of research on case painting. If you are going to paint plastic you would want a flexible primer made for plastic and Plasti-kote makes a good 1. You can paint over this primer with whatever you want. http://www.plastikote.com/products/Prim ... rimer.html
You are my hero!!! I appreciate this so very much, thank you! I've been going nuts wanting everything to be perfect & finished in time for my CPU. just searched it there is one store close by that carries it so I am in luck. Thanks again.
