I have sprayed the material,and waiting to see how it dries..and how long that takes. When the product never dries, what happens, is the gain continues to creep up over time. So far, it is dry. A week from now..we will see. The paint went on beautifully. It was thinned to a very high degree, and laid down with a Wagner power sprayer. It was laid down wet, and thin. The material took the paint very well, without filling holes at all. It should work beautifully. The gain is coming in at about 1.4, at least on the mix I was using.
