Thanks. Hey, it only takes a sheet of styrofoam, some bits and pieces found around the house, some Elmer' glue and three or four days. LOL
Seriously, it is a lot easier and cheaper than it looks and I'll be glad to help anyone anyway I can.
The main ingredients in this backdrop is a styrofoam sheet with HO railroad ballast glued to it, some metal rod, popsicle sticks and the metal mesh taken from a real car's air filter.
Remember when, back before photo etching and aftermarket, imagination was the most important "extra" you added to your kit builds?
