First off, I think anyone that has installed one of these should get a Medal or at least a Merit Badge. I watched the only 2 videos I could find and the 914rubber video clued me in on the trim tool and liquid soap. I tried doing it like Matt suggested but was only able to get about 2-3 inches installed. Even that little bit of success was a eureka moment. After this I thought my arms were going to fall off so I adjourned for the evening. I was convinced that I needed to maintain constant pressure on the seal when installing so this is what I used and DAMN it made my install easy. As in 20 minutes per side.
Good old Zip Ties

But you'll need a tool to pull the ties tight enough to work. I broke a few but soon figured out how much force to use. Start at the top and work your way down. As you get the seal in partly re-tighten the ties, rinse and repeat until seated. Work a 2-3 inch section at a time.
Trim tool - use a rag on the end so it doesn't dig into your hand; liquid soap and Zip Tie tool.
