I use Createx or Wicked Colors all of the time. Couple of reasons, 1. can paint in the basement with out any smell going through the house. 2. ease of cleanup. Between the 2 paints I can get almost any color that I want.
I also use Createx clear and it's just like any other clear, put it on let it dry and polish it out. Createx also makes a dull coating for when you want that flat look.
Createx is airbrush ready and can be sprayed right from the bottle. It's good for people that don't have a place to paint in the winter. I used it when we lived in an apartment building with never one complant.
