Rick - To answer your question

After the gray primer dried I sprayed the building with a concrete color I always use which is a 50/50 (one bottle of each) mix of Polly Scale Aged Concrete #F414320 & Polly Scale Concrete #F414317. After this has dried I spray a coat of Model Master Acryl #4636 Flat Clear. I then airbrush a very light coat of highly diluted PS Tarnished Black #F414140 over the whole structure & a highly diluted PS Rust #F414323 were required. After all of this is dried I dry brush the building to accent the high spot details with "Apple Barrel" #2608 Country Tan artist acrylic paint. I use this general process on all of my structures. With Polly Scale paints not going to be available anymore I will more then likely switch to Badger or maybe the new ones from Micro Mark (These only after I try them out). I have used Badger paints before and like them very much plus they are quite a bit less expensive (buy on-line) then any others I have found.

The Badger paints dry with a little bit of shine, but since I over spray everything with a flat coat it really doesn't matter.
