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? -Dean
