Hi All, the large windows on my recently acquired coupe do roll
up and down but kind of slowly. Of course I do intend to pull the door cards and clean / grease up the mechanisms but I'm also thinking that it might be useful to use some sort of lubricant applied into the guide slots of where the glass rolls up & down.
Slicone maintenance spray might be a candidate but I am loath to use any silicone products on trim because it can cause major problems when re-painting the car. (Which I intend to do)
Is there anything you guys use with success?
