My tenax studs snapped. I replaced them with a different version. A twin screw version with stainless screws. Raising/lowering the hood now strictly follows a routine! Tenax loosened to start and then the last to fix whether raising or lowering the hood. I've posted a photo of these new tenax studs in an earlier topic.

They are horizontal but look odd due to the phone camera angle. There is a gasket separating them from the paintwork, made from clear plastic film.
