Clear is definitely the most demanding "color."
Not when you thin it 200%! Mist on a light coat, let it tack up and then nail it till it looks wet all over. The high amount of reducer makes it go on thinner and makes the clear flow better giving a much more uniform coat. Another tip you can use is while you are spraying if you get a spot that looks dry either shoot it with a littl more clear right then or spray a little straight reducer on it, often that lets it flow as well.
