What is everyone using for weatherstrip adhesive for the rubber that needs it? Also what should I use for trim holes that perforate the body panels? An example would be at the bottom of my C pillar where there is a trim piece that mounts there and the nuts are accessed from inside the car behind the sail panels. When I removed this trim, it had an almost hard like substance around the holes to prevent water intrusion. It wasn't pliable like silicon, but more like a hard seam sealant.
