low VOC paints?

What is the best primer to use with this ? I'm assuming single stage means you don't need to clear coat it.Correct ?

I just use a high fill enamel based primer, and even a couple of different one's without a problem anywhere.
Single stage you don't have to clear, but you can do it if you wanted.
There is also some as of yet unclear information about the stuff posted has clear in the paint also, but the stuff I ordered came with a medium "wet look" hardener and I had to buy the reducer.
I mixed 8:1 paint and hardener and 4:1 with reducer and it came out like this.
