with superglue (CA) - put a filet of MB's in a joint. Drip thin CA on the joint. It will cure like a rock. Used for making super strong joints yet lightweight - such as in model airplanes. I often use this trick with the slot-a-base type minis that have a large gap.
with PVA to make snow - don't use yellow carpenter glue, use white pva. Mis about 2 parts (by volume) MB's to one part pva. Sculpt, shape, pile in drifts, etc. While it is still not cured, sprinkle a bit of alum (spice) on it to get that glittery snow-that-has-crusted-over look.
with eopxy and fiberglass, mix equal parts by volume to epoxy. Apply with a spreader after your glass has cured. This makes a sandable filler for fairing in the glass.
