I can't help with that question. You would have to call the dealer. I haven't used Dupont since they went to lead-free paint about '87.

I use R&M, which is one of the oldest companies in the paint biz. I bought some Sherwin-Williams automotive single-stage paint from my dealer, which is R&M's second line. It faded and started losing gloss in about 3 years. MY R&M does not do that in ten years or longer! There is a reason it is cheaper!
