 I have a few questions that hopefully someone here can help with . I have seen people cut white, pink, and blue insulation foam with Hot Wire cutters. But I am curious if the same methods can be used for cutting the expanding insulation foam that come in cans. One of the brands is called "Great Stuff". You spray it from the can and it expands. When it drys it looks like blobs of yellow lava. I have noticed that it has a bit of a different consistancy from the other foam. It has a more rigid shell. Would a wire cutter work on this or not. Another question is related. I have several places that I want to have high hills and valleys in foam. Should I glue these areas together then cut with a hot wire or cut then carve. I prefer the first option because it would seem more naturalistic but I am worried about the effects (messing up the cutter, ...etc.) of cutting through the glue. My last question is similar but more on based on technique. I want to make four scenes that are exactly the same. I mean the same topographey to show the same location over time. I would like to do this in foam. Any ideas on a simple trick to make four exact copies? Thanks for the help.
