Glue is whole nother topic for me ha. I've been using the standard Tamiya cement with brush and I used it on my 3D fotomat, so far so good. I've been going behind my structure builds on the inside, with Gorilla gel super glue for added strength the stuff bonds in about 10 seconds - I put a small dab in the corners or where there are joints. It can be handy in spots where you want it to hold right away because of balance issues.
I probably have at least 25 of their buildings. Pic of a few I just put together. The taller buildings are stacked pairs. I have a little bit of painting to do plus add some roof details and signage.
