What? You don't trust silicone RTV to hold your mirror? We use it
to hold our 20 ton, $4 million, 6.5 meter casting on edge for 6 months
while we clean out the mold material from the glass. It is the same
Silicone RTV with the acetic acid smell you have been talking about
for the last few days/weeks. YOu would be suprised how strong it
is before failure, typically it will sag 4X the bond thickness before
yielding. The problem may ultimately be in holding the optic without
sagging and the resulting collimation/focus problems others have
touched on. I have not seen a failed bond using RTV, have others?
