Slightly off topic here, but for weatherstripping maintenance, the Owner's Manual states: "Weatherstrips - Apply Dielectric silicone grease on weatherstrips to make them last longer, seal better, and not stick or squeak. Lubricate weatherstrips at least once a year. Hot, dry climates may require more frequent application. Black marks from rubber material on painted surfaces can be removed by rubbing with a clean cloth."

The silicone grease may be effective in most respects, but it will also accumulate and retain more dirt and contaminants than the PFPE oil. I may be nit-picking here, but the lighter synthetic oil would be the way to go. Money well spent.

That's the stuff I was referring to when I was saying how expensive it is. Thanks for the post!

Update:
All right I used the $14 Honda Shin-Etsu grease last night around the sunroof seals and so far so good. No more creaks when going over bumps or when quartering drive way entries were there is the most opportunity for noticeable body flex.

Pretty happy so far!

Not sure what why the GM stuff costs so much. For $52 its got to either filled with unicorn tears, the gold plating that should have been in the power steering rack connectors, or just simple CYA margin.
