I've been using the Kerr AccuCarve purple injection wax since last
fall. I really like it. I've dropped entire trees on the concrete
floor, and the worst that happened was a few charms snapped of at
the place where the gate attached to the charm. They usually bounce!
My basement workshop gets rather chilly in the winter, but I've
never had the wax shatter for any reason.
