Has anyone used this? Discovered it at Hobby Lobby, and for $3 (with 40% Coupon) thought I'd give it a try. What attracted me was the banner PLASTIC PRIMER, and sub-head "Promotes Adhesion on Plastic Surfaces." It apparently comes in white only. I tried it recently and the results seemed OK. Is it compatable with acrylics, enamels, and Is it as good as some of the other Krylons, auto primers and other less expensive types. Thanks for any comments. DOUG78
