Recently heard of a shop that was labeling and selling bottom to mid grade paint as the top of the line. So how do you know you're getting what you pay for? By the way, that shop is no longer in business. Heard Orielly auto parts now sell Dupont and I doubt that such a big operation would do such a thing. However I like to support the small guy and don't have much experience with Dupont. Need a single stage AU.
