Hi all. Just looking for some tips on how to install the gasket so the top corners don’t bunch up and get too thick, then the seal isn’t good. When it came from the factory it had perfect corners, and I cant get it right. Also curious what tape to use on the cut ends? They use tape in this video and I can’t find anything like it (its not foil tape, seems like cloth). This is the video I reference for the installation. His corners seem as bad as mine so I’m looking for any additional tips.
