I have had these buildings for a while, although one has sat part-painted for a long, long time. Observant readers will probably recognise the Diner from some battle reports, but the Frosty Bar has only recently been finished.
Both were built from simple plastic kits from the Plasticville range, which also includes the church I have (listed in catalogues as a Cathedral, I think) and the Aircraft Hangar which we use as a warehouse.
I purchased these from Dark House Games, whose proprietor I have always found friendly and helpful.
This just had a simple spray coat of Bolt Gun Metal, with slightly more detailed painting on doors etc. When the paint starts to wear I will go over it to create more of an aluminium finish. At the front I had to glue some plastic-card strip over writing that said Plasticville which was simple enough to do.
In gaming terms I find it a nice size to block line of sight and allow speedy movement onto and from the building. The roof lifts off which is pretty handy.
The painting has been a bit more detailed on this, with more colours, dry-brushing and washes used.
Below where it says 'Frosty Bar' there was relief writing saying Plasticville, which was filed down reasonably easily.
