Sticks like hell
Rating for the sealing adhesive: Top for roof repairs!
The sealant is easy to apply, adheres perfectly, even to damp surfaces, and remains flexible after curing. Highly recommended!

Very good
I've been using the seam closer for a week now, and I have to say, it's simply fantastic: lightweight, robust, and the black rubber caps are fantastic at preventing it from slipping off quickly. Absolutely top-notch.
