Silicone grease is an excellent lubricant for the rubber seals in a folding roof.
Following the recent mentions of silicone grease in your column, it is also an excellent lubricant for the rubber seals in a metal folding roof. After a few years the seals dry out, resulting in a lot of road noise and vibration inside the car, which I first thought was a suspension problem. Silicone grease on the roof seals cures it. I found the cheapest online from a diving equipment outlet.
A very good tip. Thank you.
