Fortunately, I Tivo MotorWeek though often find myself fast forwarding through much of their rosy, worthless reviews. Every once in awhile there is some good stuff and it finally came a couple weeks ago when Pat Goss, Goss's Garage, covered convertible top maintenance. He actually provides some great tips on lubricating all the moving parts and treating the rubber trim around the windows (and in the E93's case the folding panels too.)
Anyway, here is a link to the video. Let me know if any of you agree or disagree with his recommendations or if you prefer any other products or approaches.
