Well Surprise! I got it painted today. Got to play around with my airbrush once again and have come to the conclusion that I won't be using cheap craft paints in it anymore. After thinning it out quite a bit more than my last failed attempt I attempted to use it again and it plugged up the airgun so bad it took me the better part of an hour to get it unplugged again. What a nightmare.
After I cleaned up that nightmare, I used my Reaper and Pokorny paints to paint the house. I'm really happy with how it turned out. I did the bulk of the painting with the airbrush and the final work with paintbrushes.
I bought this house an experiment to see what I thought of the Tabletop world things and all I can say is their products are amazing!
