For what it's worth, I use the 3M sealant to attach the rubber to the glass. Then let it stay overnight. Then put oil on the rubber, people say the rubber will expand over time due to adding oil. Then put the channel on, have it laying flat on the bench, starting with one end and then pushing it on using nothing more than your fist. thereafter the rubber will expand (oil). Giving sufficient pressure to hold everything together.
