Ok, honestly was getting frustrated with my inability to paint a convincing cement surface for the inside of the hanger, and I was not even considering the concrete apron outside! How can this be so hard!!!
A few months later I found THIS video and decided to tried again:
Also, I changed up airbrushs. I packed away my single action badger and hooked up my dual action Paasche Talon for the first time. I was hoping that the gravity feed on this model would eliminate the constant clogging or non-suction of the Badger. (Spoiler alert, so far so good!)
I applied the Tamiya Fine White Primer (this is like the third layer primer) which went on like a dream straight from the spray can(!), then the NATO Black and this is what I NOW have:

I find this photo a little confusing, but the top is the inside of the hanger and the bottom is the apron. Next up is the part that usually turns it into crap when I try it. I have to fill in the entire area bounded by the black lines, and a little over, with Tamiya Neutral Grey. I have to cover it in its entirety and yet not so heavy that the black "seams" don't show through. Seems simple enough, but I keep screwing it up...
