I’m working on modeling the inside of an engine house in a shadow box for my “Winter Project”. I want to put a corrugated roof, and then the splines, trusses and beams. So to a piece of 1/2 inch plywood, already attached to the basement wall, I want to attach corrugated aluminum panels 1 inch by 3 inches long. I thought about contact cement, but you get one shot. So maybe silicone? And then some type of pressure to hold it while it kicks. 5 minute epoxy? Ideas?
