Eventually it'll do the same as JohnW R8 rear view mirror :(

Standard silicones utilize acetoxy or oxime cure mechanisms, releasing acetic or ketonic acid fumes, which will corrode copper and other metals.

What you need is a 'Neutral Cure' RTV Silastic.
By using an alkoxy cure, electronics grade silicones release only non-corrosive methanol, which is not harmful to sensitive electronics.

Hence my question. I used Tarzan's Grip though, believe it or not. Happily I can easily get another mirror cut if it misbehaves. I'm glad that Selley's information sheet requires me to wear safety boots when using the product. :)

Thanks for buying into some of these discussions Alex! Appreciated.
