when i lived out in chicago land i worked in a trade show display (and educational displays ie: cutaways) shop. we used nason for quite awhile because it was cheaper and looked just as good as regualr dupont. then a ppg rep came out and since the day i met him i have been happily hooked on ppg's fleet line called del-fleet. very very good product. great coverage and color too. been quite some time since i have been in a booth though. hopefully for the ole trucks sake its not forever before i get back into one either. but as far as the nason goes. if you can find it super cheap gobble it up its good stuff. my $.02
