I've just laid the first level track for Turkey Hollow and I have a few months before I start the first steps away from bench and track work toward scenery. This is all new territory for me so I want to explore the different options available for covering cardboard lattice work. I want to create a base layer between layout levels (10") and between sub-roadbed.
I have watched both Rich Melvin's video demonstrating Hydrocal and Eric Siegel's videos where he uses Alumilite foam over fiber glass window screen. (I have a roll of aluminum screen I might try to use.) Both materials seem to be somewhat easy to use and work with. I know that I can get small amounts of both to experiment but I would really appreciate hearing from those who may have used these products, or something else. I have to admit that I am a little biased against Hydrocal because in my mind the weight can add up fast. Perhaps one product works better in some applications than others?
Thanks for your input!
