I used white lithium grease in a spray can. But the next time I lube it I might switch to silicone spray since it is plastic on metal. The OEM is a grease instead of dry so I am sticking with a grease.Over the past few months, I have been having an issue with the sunroof shade not sliding like it should, and bunching up in the front while retracting. I the sunroof a lot, and when off-roading, its subjected to a ton of dust, so not unusual for it to need cleaning and lubed. I cleaned the first time using a rag as I didn't have any qtips. I then used some white lithium spray grease to lube. Unfortunately I got the PB blaster kind, and it smelled horrible. I then used qtips to clean it out, and used a generic white lithium spray grease. It still bunched, but only when its hot outside, and even more in direct sunlight. When its cooler, like in the mornings, no issues with it bunching. I cleaned again, and used a LIL-Glide (a silicone lubricant type product recommended by a youtube video I watched. I applied it with a qtip as well since it comes in a squeeze tube. Still the same end result of bunching when it was hot. The grease that was originally there was black (or at least it was black when I took it out). Does anyone know what product to use to lubricate the power sunshade?
