I've used Tamiya Silver Leaf on plastic for a "color barrier" and never had any paint "lift off." Over the years I've also found Testors, Tamiya, Black Gold, MCW, and Dupli-Color to be compatible with each other. In the last few years I've been using Tamiya Primer and I know that it's pricey, however I get good results with it and you can get it at Hobby Lobby with a 40% off coupon.
