What the heck is going on here? I tried to paint my own clearcoat. It's like, when i paint one 1/2 of the roof, then this "stuff" gets on the other side of the roof, and it hardens, this leaves the surface very unsmooth. So when i go paint the other side of the roof, since its unsmooth, i end up spraying ALOT more than i really should if it was smooth. As i spray that 1/2, then the same process happens with the other side that i just got done spraying. Im using Nason 496 something. Am I mixing the activator correctly? Or am i using too much air? Im on the edge of taking it to some pro and spend $400.00. I thought that i could do it myself and save a few hundreds, but im paying the price of it.
