Thanks, guys!!
Last night I tried to start on the 2nd Tillman Farm House. I started by identifying the walls that would be used. Since this was going to be lit, I decided to paint the interior walls black to prevent that "glow" that sometimes happens with plastic structures. Unfortunately, the paint can nozzles (a bunch of them) were clogged and uncooperative. I watched a couple of YouTube videos on how to clean them. Today, I bought some lacquer thinner, soaked a few nozzles, and was able to paint the backs a flat black.
A few hours later, I flipped them over and hit them with the flat white for the exterior.
I'll try painting the roof sections tomorrow.
More when I know it.
