I live in an area of Sou. Calif. that has population of about 2 1/2 million. Only know of one store that handles Nasson. Whereas there are five which handle Dupont, and about twenty that handle S-W. Perhaps in the mentality of In and Out body shops, they find the Nasson too much trouble to batch up on a whim for a customer and thus is not handled. Which is why it is not used for simple fender benders.

Overall, I think most paints too expensive anyway, and I have been spraying on the stuff for more than twenty years. And I flat do not like to visit the stores due to sticker shock.
"You sure that is the cost per can?" Sheeesh, last time here it was...."
