Okay, I will try to provide some insight here. Definitely go for the least expansion you can find. I have used a latex-based foam filler made by DAP called DAPTex fot filling a large space between pieces of foam on a small diorama. After I applied it to the needed areas I put a bag on my finger and basiaclly formed the foam. When it had cured, it was soft and white like a marshmellow. I was able to do the fine forming with a wire brush on a Dremel. When I was ready, I painted the entire diorama with flat tan latex paint. I noticed that when the paint dried, the paint shrunk a little, taking the foam with it. The foam was pulled back around the edges about 1/8". A few years ago I used the brand name Great Stuff for a project. It dried yellow and hard and alowed me to carve it. Both of these foams, when cut, are found to have a texture filled with many little bubbles because it is FOAM. The blue and pink foam board was made by putting foam into I believe mold-type objects and compressing the foam so it is NOT filled with little bubbles so it is more dense and a better insulator. Granted, if you are using this foam filler as a base for carving rocks, these little bubbles will cause a problem. I don't know if this foam can be cut with a hot wire foam cutter will cut this, but if it can, that would solve all irregular texture problems. If this foam is going to be used as ground with ground foam or a similar material over it, then the tiny bubbles will not be a problem because they will be covered and will not be visible. Personally I would go with Great Stuff because it cures hard so it will not pull back when painted. <br />Basically I say that this material is a great land-form filler, especially Great Stuff. <br />Reed
