Not yet! I’ve got a bunch of old mates coming to town and I’m focused on detailing the Spider. In the meantime I’ve developed a habit of just giving the seatbelt a little assist as I remove it and that’s taken care of it for now.Did you try cleaning your seatbelts ?
Actually, I think you might be more correct, as I'm staring at the two pics, and realizing that the darker blue reflects an increase in the vacuum. Now I'm more confused; wouldn't that be more drag?
