I have used dozens of gals of the Summit acrylic urethane's in my work for non automotive or truck use. Its decent and affordable. I still have usable on the shelf a bit of the original Dupont IMron paints, my favorite.
I have used gallons of the Summit brand DTM epoxy primer, Did not impress me, and not likely I would buy it again.


Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
