Justin, what part of California do you live in? Arnies' Trains in Westminster now carries blue foam. Home Depot carries a brown foam with an aluminum foil type coating on one or both sides (don't remember which). According to Bragdon Enterprises in one of their work shops I attended at a train show, the aluminum backing peels right off and the foam can be easily cut with an old steak knife.
