I have leaky gutters where they meet at the corners. I don't mind them so much in warm weather but in the cold/freezing months they are a hazard. They leak/drip and the water ices up on the ground underneath them that I have to either keep a bucket to catch the water or have rock salt on hand all the time to keep the ice at bay. So when I got the Flex Seal Spray Rubber Sealant I thought this would be the answer to fix my problem. I gave the can a really good shake and followed the instructions to spray where the leaks always happen. I sprayed several coats with time in between to dry before spraying another coat. I was disappointed at how thin, watery and messy it is to apply. I was hoping to build up a seal BUT that did not work. once it rained I wasn't surprised that it did not work and it seeped through the leaky joint along with the rain water. I wound up having to wipe it off and clean up the mess. This says it works on all types of material wet or dry and sadly the results were NOT what it promises to do. Others may have a different experience then I did but for me it just did not do the job. [This review was collected as part of a promotion.]
