Rated 5 out of 5 by from Does The Job I've used this a few of times and it has held the water every time. It's very rubbery which makes application a bit of a struggle, it also dries very quickly so you'll need smooth it quickly after applying. Saying that, it does the job and fixes leaking gutterings.
