Rated 5.0 out of 5.0 by Did the trick! This product worked great. I had a small leak that was dripping on the downstairs ceiling tiles. I used the Rustoleum Leak Seal product and it worked as stated. The dripping stopped and I was able to fix the issue upstairs, replace the ceiling tiles and no issues for over 1 week. I would definitely purchase this product again. August 30, 2016
Rated 4.0 out of 5.0 by leaky barn roof goes on easy and coverage is good. put this on last evening and now i am waiting on rain. If the leaks are gone then I will change ratings July 26, 2016
Rated 5.0 out of 5.0 by Better than expected My vinyl spa cover has deteriorated to a point that it lets water in from the top when it rains or gets wet. I bought this Leakseal spray to see if it would at least get me through the winter. This product has worked better than I expected, it is flexible and does not let moisture into the hard foam under the vinyl cover. I recommend this to anyone who needs to stop a leak. June 16, 2016
Rated 5.0 out of 5.0 by Used for rusty metal fence posts for chicken-wire type fencing. I took as much rust off the metal fence stakes as I could, which wasn't much Big clumps of rust remained. Then I painted them with Rustoleum paint, then this sealer, then with paint again. I think they'll hold up. June 28, 2016
Rated 5.0 out of 5.0 by Works great This product worked great. This is the second time we have used it to paint our window wells and it holds up great May 31, 2016
Rated 1.0 out of 5.0 by rustoleum leakseal flexible rubber coating This product was garbage. It is not recommended if you plan on sealing over any caulked surface. It will not adhere. February 16, 2016
