Over the years I have used many gallons of Nason products. In fact I used to take care of a fleet of taxi's and Nason acrylic enamal held up better than Dupont Centari. Nason was the oldest paint company in the US when Dupont bought them out a few years ago. They were mostly a fleet finish mfg. One of the reasons it is cheaper than Dupont is there was little or no tech support from them other than counter help at the store. I think it is an excellent product although after 50 years I do not paint any more. If oyu think Dupont is pricey check PPG.
