Who makes good paint?

I feel top coat to be most important for Durability and fading. You could use Omni Base coat to save $$ then PPG , Dupont or other Quality Clear. The main reason I like PPG is their DP Primers , it has good adhesion and acid etching for bare metal (rust protection) properties and special hardener for plastic bumpers . Use could still use DP and use a cheaper 2 part filler primer like (Trans star) to get your bodywork blocked out.
