I am just beginning with these as well. Two things I have found.
-Too much thinner is very bad. i went by a recommendation that I had seen online and mixed it 50/50 with its own thinner. I felt I was in a marathon with all the running. Less is more with this paint. Put a drop of thinner for every six or seven drops of paint. If you spatter add more but drop by drop.
-It looks like it sprays best over itself. My first attempt I sprayed over my normal base coat (Rustoleum Flat Black) with miserable results. i got frustrated and put it down for a couple of days. I went back and sprayed again after a couple of days to try to figure it out and it sprayed very nice as long as it was over the parts I had failed at before.
I am learning more each time and hope to figure out how to blend it like I do enamels but that will come with time, I hope.
I do hope this helps some.
