Cold Weather Noises in Top

[1JB]

Now that the weather is cold I notice that with the top up the right kind of bumps cause a clicking or low pitched squeak like noise from the area of the plastic inserts between the top and window. It's not much of a bother and but I am wondering if anyone has found a lubricant or way to stop the noise that seems to be made by these cold plastic components bouncing together over bumps. I really don't want to have the dealer fiddle with it since they tend to pull things apart and learn as they go on an issue like this. Thanks.
