I have a customer of a customer who works for one of the big three automotive paint companies. I asked him specifically about the cheaper paints in connection with the "paint it all for $300" outfits. He said that they all made paints for other labels....but they were NOT made to their premium formulas and were not necssarily to their quality standards....in other words, the off brand label is made to order and cannot be considered an "equivalent" to the name brand stuff. So, just because it may be made in a Dupont plant, dont ever think that it is "similar" to Dupont! Funny, just like in everything else, you get what you pay for.
