Is there anything anyone does in relation to that retractable window up on their roof? Just curious if we're suppose to lube the tracks or anything else for that matter.

 

The track has a light grease on it from the factory. It does collect dirt after a while. I've cleaned it up with WD-40 and a rag, then applied a very light coating of grease to the track. Don't gob it up with grease or you'll wind up with a mess as it collects dust and grime from the road. Also clean out the edges & drain tubes using compressed air or your garden hose. Just a quick blast should keep them clear. Apply some nice rubber protectant to the window rubber to prolong it's life as well. I just use tire dressing or the leather cream I use on my seats and door seals. That keeps it quiet too.
