Carlos: thanks for the tips. I use a single-action AB and will fiddle with a double-action sometime in the near future. I usually paint large areas at about 20 psi and camo stripes/patterns at about 10-15 psi. I use MM enamels thinned 50/50 with Testor's Thinner (red can).
I'm not building a Ho, although watching your build has made we want to, I'm part of the ground-support Rabble.
Again, Awesome (an over-used term, but appropriate in this situation) result with your Ho.
