If you really want the best, buy some Dow-Corning MolyKote D-96. Usually you can find it in an industrial coatings plant, automotive interior specialists, or have Granger order it for you.

You can also get a small sample sent to you. I have had 2 shipped to me already. Comes in an itty bitty tube that's good for about 3 years.

You can also call the folks at www.krayden.com and have them send you a big bottle for the really big squeaks...like a passenger that's pissed you are driving your XF too fast.
