In my last post, the idea with this scratchbuild was to take easily available materials and make an N Scale skyscraper. The basis is a window/floor framework printed on regular 11'x17' (tabloid) paper- generously coated with spray paint on both sides - and some clear acrylic 'baseball' display cases.
I switched colors from the brown I had previously, using "Euro Grey" from Model Master spray paints instead, and I ditched the baseball display cases as the 'foundation' since the edges didn't glue level and I knew the seams would be noticeable. I substituted regular clear acrylic sheets as an alternative (these are available at the local hardware store and can be cut to the size you want generally).
I also wanted the windows to be a bit darker, but not too dark. I used 'Transparent Black Window Tint' from Model Masters, which turned out a lot better than I expected. Below are 'before' and 'after' shots:
