Re: Squeaky Windows
I know people do use it but silicone spray on glass is not really recommended.
Its a good rubber lubricant but its better not to use it on glass. It causes smearing and once applied it cannot be removed, so particularly on windscreens, any car maker will not use it (silicone will contaminate the glass and car makers take care it does not come in contact with any glass).
I know on side windows its less important about smearing but personally I would not. If you must, I would wipe it sparingly onto a rag and then just on the edges of the glass.
To stop squeaks french chalk or talc is used by car makers. Clean the glass and use a good glass polish (Autoglym?) and apply french chalk or talc to the rubber.
Possibly some of the 'flocking' (felt-like appearance) on the side runners or waist seal has worn off, so it really wants replacement rubbers.
