I am fortunate as my top is quiet, not a sound out of it so far and I have removed it at least 10 times. I want to keep it that way. What, if any, product should I use? I have always used Gummi Pflege on the rubber seals on my other cars. What about the pins and recesses on the top and the car? What should I use on them? Is lubricating the top something the dealer will do for free during an oil change? If not, I will do it myself but I want to do it right and use the right product(s). Thanks.

When I had my C6 the dealer lubed my top for free when I had it in for an oil change. I would just call the service dept. and ask them what they use if you want to do it yourself.

Do it yourself and use the above mentioned products. I use the Dielectric Grease. Good stuff.

When I get noise from the roof it has nothing to do with the rubber seals, agree though a it is a good thing to keep a silicone lubricant on them or similar.

My noise always came from the latch itself , where the striker meets up. The two parts shifting against themselves on bumps etc. is where the noise is generated. I found success cutting a bicycle tire inner tube , takinga a 3/4" piece and locking it in place between the two parts when I closed up the roof. This stopped the two pieces from sliding against each other.

Last fall I had the new parts installed, striker and pins, yet to find out if that provided a long term solution as the car is still in storage waiting for spring. Crossing my fingers, if not I will go back to the rubber. It worked 100% of the time. Before that I had tried all the other solutions provided on the forum, 0 rings etc.. nothing had worked.

I have some dielectric grease and just ordered the synthetic lubricant from Amazon. Thanks.

For the C6, GM recommended the dielectric grease, changed that to the synthetic with Teflon, and then changed back to the dielectric grease.

I have not experienced the noise with the C7, but when I do, I will have the dealer update both the front lift off panel strikers and both front locating pins per bulletin #15-NA-016 (Creak or Snap Noise Above Windshield from Removable Roof Lift Off Panel While Driving - Sep 30, 2015.

Now that GM has a bulletin for the repair, don't try to lubricate and possibly not be able to take advantage of the repair under warranty.
