Sunroof Operation

I made the mistake of opening my sunroof today, its only about 30F outside. It opened fine but when i went to close it, it went about 3/4 of the way and stopped. I then opened it all the way again and closed it, this time it went practically shut but it still stopped. I had to press the button several times to inch the roof shut. I dont even think it fully sealed shut because I looked on the roof when i got out and there was a section of snow all melted towards the front of the opening while the rest was intact. I was thinking about spraying some white lithium grease or WD-40 on the tracs is this a good idea? Is there somthing else i should do for it??

MB reccommends their own brand of sunroof rail grease. Use that ONLY. Any other grease or lube will attract dirt and only make things worse. The first step is to open the sunroof, and clean the rails with some WD-40. Spray the WD-40 on the rails, then wipe it off with a clean rag. Then, apply the grease on the rails, and open and close the sunroof a few times to ensure even distribution of the grease, and you should be set.[:)]
