The sanding actually makes the paint almost slick like. The other thing is the blending. You have to almost flick your wrist with a small quick snap of the wrist in order for it to blend properly.
I will give one piece of advice on another brand of paint. Matrix. DO NOT USE THEM!!!! Matrix SUX!!!! I have had nothing but issues with their product. Its almost impossible to blend, the clear does not lay well, and actually settles a bit after it is sprayed. This makes it challenging trying to get it wet without running it.
