Thanks, G. It should be a snap to finish, though somewhat time consuming. Most of the smaller items for the bunker (lights, junction boxes, access ramps, etc.), will be scratched up, then multiple copies cast, saving me gobs of time. One of my biggest problems to overcome, will be to recreate the effect of the wooden forms markings in the concrete finish, but I think I have a handle on that; we'll see, I guess.
