I did weather the roof with several different colors of dusting powders. I used some from Micro Mark and Bragdon. I used Grimy Black, Dirty Dirt, Rustic Rust, Burnt Sienna, Faded Grime and Dust for the colors and randomly applied them to the roof shingles and smoke stack. You will be able to see the overall affect in later photos in the thread.
I then moved tot he warehouse roof. The bright red was subdued with dusting chalks and powders. I used Light Grey, Grimy Black and Dirt Tan on the tarpaper roof.
I started the install the roof sign but first added the three roof sign braces to the roof. I marked where they would be located on the roof and glued on the supports. Of course, I had to add my nut and bolts to the supports.
I then built the warehouse roof sign. The sign I used comes with the kit. When Jim built the diorama Boilermakers, he used the Black and White sign for the roof. I liked the one I used so we could see a different sign with more color. I cut it out and lightly sanded both sides of the sign. I built the sign billboard per the instructions.
