I have a "Guppy Mouth" C model with a doghouse instead of the more common baffling. The rubber that seals the cowling to the engine compartment has deteriorated after just 41 years.
I found the rubber material, but am trying to figure out the best fasteners to use since the only stapler I have is a desk stapler.
I have considered PK screws and pop-rivets, but am wondering if anyone else has replaced the rubber seal and what they used, or what you Mooney gurus out there might suggest.
Picture attached. (Hopefully.)
