But my top has other problems - the deck seam on the driver's side has seperated, beginning at the rear support and continuing toward the rear of the car. Not much of a lifecycle for a car with only 26K miles.
I glued the seam with Loctite Fabric glue using black duct tape as backer material. So far it has held through a 1K mile trip and a lot of rain. I've had this car just 2 months and am unimpressed with the top, as well as the cup holder, which broke on this last trip.
Top shops won't fix the seam but will gladly install a new top for $1,799, including installation. I'm saving my pennies...
