The Nason Chasis Black didn't seem to dry hard enough. I did half the frame and all of the rear suspension and axle with it and i looks good but it didn't seem to dry hard enough. I Set some things on the frame a week after i painted it and when i picked them up it seemed to stick and pull paint off. This is the pre-mixed stuff and i used rustoleum primer underneath it. I was very disapointed with the outcome of that paint. After i saw this and started looking for something else to go to i noticed a lot of bad reviews on the pre-mixed nason as well. Its a lot cheaper but i wouldn't recommend it. The urethane is more expensive but is supposed to be more durable.
