Interesting...I just read last night of someone that uses Dry Wall "mud" (it was late, and I don't recall who or where). It got me to thinking of those hand little jars of spackling for filling nail holes; and I'm wondering if, for thin applications over foamcore board, if this might work? I imagine there may be some shinkage/cracking issues if not done right, but I may give that a whirl.
