David,

Three small dabs of silicone caulk with a diameter of 1" will be sufficient.
Both surfaces should be clean. The supports should be spaced at 120 degrees
from one another and 1/3 to 2/3 out from the center. A mirror this size is
VERY forgiving where the supports are placed. To improve air flow, the disk
doesn't need to be the full diameter of the mirror. You can also drill a
hole in the center. I would recommend using a disk of plywood (won't warp
like a solid piece of wood can) 1/2" - 3/4" thick with a diameter of
approximately 3". Be sure to maintain the separation between the mirror and
plywood disk with a few washers while the caulk cures.

Albert
