Nothing sticks to glass better than Silastic. They use it to lift the 8 meter VLT mirrors
Sure if you have a 9 point cell ( 3 flotation triangles ) use them, but 9 dots placed on a board is not a floating cell as any warping of the back plate will be transmitted to the mirror . A single ring flotation is extremely forgiving and gives excellent results on 14" and under mirrors, in fact better than a 9 point cell. I have mounted 3 mirrors between 14" and 12" with a single ring of velcro and it works superbly. I pipe up about it every now and then when questions like this come up.
Use Search function and you'll find plenty of prior dicussion of it. Have fun.
