After reading all of the posts in the archives about being sure to use the right lubricant on my 300E's sunroof, I stopped by San Antonio Mercedes and bought some. $28 for about a pound! Holy sheepdip! Obviously, I now have a 500 year supply on hand. If anyone else would like some, just email me (email@example.com) and I'll send you some. If you wanted to send me a buck to cover the postage after you get it, that would be cool, but this list has saved me tons of $$, so what the heck.
