Probably. The sealer that's supposed to be used is butyl not urethane. 3M 08509 is what I used on the quarter windows. It isn't difficult to remove. I'd redo it now rather than waiting and finding I have a leak. I wouldn't I risk a leak on the installation based on a possible replacement in the future, anyway.
I haven't installed mine but based on the removal it doesn't look like it'll be that difficult. With the locking strip peeled back it seems like it'll be easier to install than the quarter windows were.
