Rated 4.8 out of 5 by 4 reviewers.
Rated 4.0 out of 5.0 by Overall good The earlier review is correct this product does not work well on a damp surface or underwater. But on a dry surface it works extremely well. it is definitely much stickier and seems more durable than any silicone or latex caulk I have used. I used it to reseal my gutters and so far it has worked well. August 14, 2013
Rated 5.0 out of 5.0 by "This Product is True to it Features and Performance". I, James, have tryed other sealers but this is the best i've used yet. I 'll put it out front of all other gutter sealers. So, I commend Amerimax for a good job well done. Thanks ! October 1, 2013
Rated 5.0 out of 5.0 by works well used a putty knife to smooth the caulk into the gutter connections and so far no leaks. Seems like a good product. June 16, 2012
Rated 5.0 out of 5.0 by Better Than any silicone out there This was recommended to me by an old time tin banger. Said it was the only one that really worked on old seals . That's the truth in my experience December 10, 2013
