- I was walking through the hardware store the other day and saw a
- product that *must* have some good use in model railroading. :)
-
- The product is aerosol foam, intended for filling gaps around the
- house to stop drafts and to insulate. You can squirt the foam into
- any irregularly shaped space and the foam will fill the void, then
- harden. You can cut or carve the foam with a knife after it hardens.
-
- I'd like to hear if anyone has used this product. How "stiff" was the
- foam when it came out of the can? Could you make a free standing
- mound of the stuff, or is it pretty "soupy"?
-
- It strikes me that this might be a quick and easy way to build a
- foundation for mountains. Squirt a pile of the stuff on a corner of
- your layout, let it harden, do some rough shaping with a knife or a
- Surform, then cover with Sculptamold (or whatever).
-
- Potential advantages: less mess than carving bead board; no framing
- members needed as with hardshell techniques, thus less weight (a plus
- for portable or modular layouts), ...?
-
- Possible problems: you'd have to make a cover for your tunnel tracks
- to keep the stuff away from the right-of-way; leaks in that tunnel
- when squirting could cause a messy "cave-in" that might be hard to
- reach/fix; ...?
