That's interesting Peter, my 2012 +8 leaks in all those places. It's encouaging to know those small improvements work - a trip to Malvern for some foam beckons. You say silicone grease on the header rail works to keep rain out too? Any particular sort? Thanks, Alan
I used a version of this:
Kryotox I actualy got mine from a place that services pools and spas. But any flurosilicone grease containing DuPont Kryotox will work. DO NOT use a straight silicone grease, it will destroy the rubber over time. Kryotox is a flurosilicone and is totally bon reactive when in contact with modern synthetic rubbers, it keeps the rubber soft and extends its life, as well as keeping out moisture.
VW/Audi sell it (at an insane price) to lubricate the rubber seals on their convertivles.
I also use it on the Merc, the frameless windows creak in the seals if not kept lubricated.
