nice start, Don...As friends Evan and Andy say, remember the aluminum for the gaps...
Regarding the paint, it seems that it is very thick, not very diluted, that is why the layer of paint is so thick, it could also be a question of the air pressure or even that the needle has too much travel, I usually do the paint dilution directly in the airbrush and I add 2 more drops of thinner than paint. I paint at very low pressure, I have never painted beyond 1.2 bar and with little needle travel, always thin layers...
