i don't say this to be snarky, but if you make the video title shorter and use more keywords, you may be able to get lots of random views on it. you could very easily be "that guy with the hyundai sunroof trick". it's a very thorough video, i don't want you to have it not get the recognition it deserves because of bad titling and such!
a tip: i recently used a small foam paint brush to apply on the lube. you can find those at arts and crafts stores or dollar shops. In my case, i use WD40 Waterproof silcon lube.
are you sure the lithium grease is OK for the rubber? i researched a long time before learning Silicon is the safest for weather stripping type of rubber as it won't dry it out or crack it like other greases.
