I have a 1990 W126 coupe with electric tilt-and-slide sunroof, but I think this question applies to all MB sunroofs. To avoid expensive problems when the roof jams, lubrication is vital. But what lubricant should be used?
Browsing the forums (esp the US ones) reveals a lot of dire warnings that only the original MB lubricant (gleiptpaste?) MUST be used. Problem is, the real stuff is only available in, or from, dealers, in big tubs (why?) and at huge expense.
So what are the possible options? Most advise strongly against the cure-alls like WD40, and also 'normal' lubing oils or grease, which either hardens with age, or attracts dust and dirt. I have seen recommendations for PTFE (spray?) and silicon lubricant - but I'm not sure if those 3-in-1 cans from Halfords are good enough, or if they're just normal spray-oil with a little of this stuff added. I have also seen mention of cycle chain lubricant containing Teflon (PTFE by another name?)
Any thoughts/comments/suggestions? I'd hate to use something only to find that it gums up the slides...
(Psst - if anyone has a tub of the real stuff, can I do a deal for a thimbleful?!)
