I brush painted the various parts using Floquil paint.  This worked well on the wooden parts, but I should have sprayed it on the floor.  The outer roofing was really easy as it was basically a large sticker.    I really like the way it looks, when painted I think it will look like tar paper.  Using this outer covering helped me out on the cupola as it covered a crack that happened in the sub-roof as I was gluing it into place.

Also when building the cupola, I discovered that it was possible to position the laser-cut parts approximately where they were supposed to be, and then use an x-acto knife to do the final alignment.  The knife was also useful in pushing down the small parts to set them in place.
