Since this is a pretty handy crew, I'm soliciting suggestions for tightening the driver-side mirror on my venerable Escort.

It's a simple ball-and-socket, with no provision for tightening it. It's old enough that on very hot days, it loosens up enough that air flow at freeway speeds is pushing the mirror out of position.

Any suggestions on how to tighten it up without permanently fixing it in place? Is there anything like Loc-Tite that would just increase the friction?
