I have done 2 complete paint jobs with Nason base/clear they came out great and are holding up well. as said they are Dupont products. the only drawback is there is only one formula for each color, no alternates. so they are fine for a total repaint but are not good for repair work. I have found nason clear to be better than chroma clear at about half the price. I have pics of the jobs if you want them. good luck
