    Recommended lubrication for glass / rubber guides

    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?

    I'm wondering if the infamous Gleistpaste might do the job? Others might chip in whether's its suitable or not. It's damned expensive if you have to buy any. I've got a tub full, and could send you a little jar full if you like? Email me if that's the case.

    Hi Stephen, many thanks for your kind offer. I do actually also have a new can of Gleitpaste myself

    Gleitpaste would maybe smear up the glass on this application. Perhaps silicone spray is about the only product that will help - if applied carefully with a straw to direct into the rubber channel.

    Or is it a case that lubing the mechanism first and foremost will make the biggest difference?

    I think I'd start with stripping out the door cards and having a good look at the window winding mechanism. You never know what you might find. I did this on my 500E, and found various bolts loose/missing on the window winders which couldn't have helped for a smooth operation. I then used the Gleitpaste to lubricate all the gears etc., and you're right, I found that its best to try and avoid getting any of it on the glass. Its very persistent (which is good on the one hand), but difficult to get off the glass.

    I guess its best to assume that MB wouldn't have used any lubrication on the rubber runners when the car was new, so in theory one shouldn't need to use it now?

    All the best.

    By the way, do you know if face-lift left-hand drive, but left dipping (for UK roads) complete headlamp assemblies incl. lens, are still available? I noticed you got a pair a short while ago, but when I tried to order some from my Germany supplier, I was told they were NLA. Maybe your's were pre-face lift?

    Any UK MB dealer will be able to advise on this Stephen – I am not sure of current stock. What you could do is get the correct used LH Traffic housings and new E500 lenses to fit onto same. I have pairs of good LH traffic lamps available (120 for the pair) if any use.

    I have used Gleitpaste on the edges of the glass mating surface/and on the rubber. You don't see it because its the edge, and the window is either opened or closed either way. It does make things slide a bit easier. Just put some in the channel for the last 5-8cm of the rubber where the glass has the most pressure/contact.

    I have used product that should fix leaking automatic transmission seals. But it seems to work very well for rubber seals, it makes them black and soft again.
