Front window rock guard arms
My Windjammer has two front windows (one on each side of the “V” nose). Each window has a separate rock guard on the exterior.
The rock guards each operate on two aluminum sliding extension arms with wing nuts to tighten when in the “open” position. Sorry I don't have photos. I assume other TTs have similar rock guards with aluminum arms.
My question is what lubricant or other maintenance anyone has found helpful to keep these arms sliding smoothly? The arms have intermittently become uncooperative, requiring a fair amount of force to close, which has to be done very carefully to avoid the risk of bending or breaking something.
