Thanks Mark! Take a look at the stacks now... I airbrushed them a mixture of a new color from Tamiya "Dark Brown" and added a little bit of flat aluminum creating a burnt iron look with a little metallic sheen. I then airbrushed the insides of the stack top and some of the outside of the top with some flat black. I think it's looking very real and I haven't removed any of the top coat to reveal the "rust" underneath. Thinning the top walls really shows up now and makes it very hard to identify it as a piece of 1/2" CPVC domestic water pipe from Lowe's. In this picture, they're sitting on the handles of some larger paint brushes... a convenient holder for tubular painting jobs.
While this was drying I completed the other half of the roof shingling. I still have to add the peak caps on the little side portions.
Next up will be finish the stacks, install them and add the guy wires. Before gluing them in place, I'll age the roof a bit so I won't be doing this with the guy wires in the way and causing a problem. I also have to put some "tar paper" on the little corridor roof and put some capping tiles on the wall's parapet top. With those steps, I'm just a few days away from installing this new structure on the layout.
