Slow Drying Weatherstrip Adhesive?

[ProTouring442]

I am looking for a slow drying weatherstrip adhesive... :willy: I have a car where I will need to position, move, reposition, the weatherstripping to make everything seal properly. I know about the black weatherstripping adhesive, but that is a contact cement. Is there any such thing as a slow drying adhesive made for weatherstripping, or should I use RTV Silicone? :goofy:

Any help would be greatly appreciated!

Thanks!
Bill
