Works really good and takes no time. I used the black rtv sealer/adhesive. Had to remove some of the rubber that was to far gone. Then pressed out on the corner of windshield and worked the rtv into the channel. Then I applied pressure on the outside corner of windshield until the rtv started to set-up. I then put another bead on top of the first. Now I wet my finger and used it too form the rtv into a better looking bead, keep your finger dripping wet and the stuff don't stick as bad. You have to work quick if it's warm and humid, the kind of rtv I used sets up really fast.
