This originally was the gray with black roof version. As is often the case when you're learning on the fly I assembled the kit before I realized that this "unopened" kit was missing half of the roof and that I would not really like the looks of the gray building.
First I made a new roof out of 7/16" 4" x 24" basswood from Michael's. Then I covered it with two pieces of roofing ice shield from a roll I have at home. Once they were glued in place I made roof vent caps out of the same material to cover the peak seam where the two pieces meet. Originally I tried weathering the roof but not liking how it turned out and not being able to get the weathering off I sprayed it with flat black paint. Unfortunately doing so covered the sparking grit in the ice shield.
Once assembled I didn't like the grey plastic building so I searched the forum and spoke with Alex M about redoing the building. Spraying it with Rustoleum Rusty Primer after I taped off the Windows and doors and then applying Robert's Brick Mortar Treatment seemed like the way to go.
Here are two photos of the long walls. Need to reinstall the front doors and paint the rear wooden panel section. I installed lights inside and think I'll add lights over the front door, the side door and the sliding loading door.
Will post more photos as I go.
Suggestions on what to do with the roof and/or anything else is appreciated.
