Rated 4 out of 5 by from Works great, but be patient [This review was collected as part of a promotion.] This is a great product. It setup and sealed even styrofoam ( without melting it ), the biggest concern is being patient. To seal something faster the tape is a better option. This product reaches all the nooks and crannies that can cause leaks. Thumbs up to this product.

Rated 5 out of 5 by from This is a must have in any DIYer’s toolbox [This review was collected as part of a promotion.] Keep this where you keep your duct tape. This is an easy fix solution for a number of situations. It fills and expands quickly and dries in minutes... though it is best to give more time to cure. I may not use this in areas that are outside and directly exposed to sun and rain.

Rated 4 out of 5 by from Works as intended [This review was collected as part of a promotion.] I used this product to help seal up the vents in our crawl space for winter. From what I can tell, it seems to still be holding up, 9 months later. I have not tried this product to seal an area with a high moisture environment.

Rated 5 out of 5 by from Works Well, Does What It Says [This review was collected as part of a promotion.] Flex Seal does exactly what it says it will. It provides a rubberized water tight barrier that can be sprayed on and is safe and easy to use. Working with epoxy and testing is a little too dangerous for my liking, but the flex seal worked really well.

Rated 4 out of 5 by from This stuff works for the right job [This review was collected as part of a promotion.] This product worked well for me for a variety of uses. I was able to seal up a leaky jon boat as well as a large plastic pond tub. It can be used on most any surface and does a good job of sealing things up in a pinch.

Rated 5 out of 5 by from Really good sealant [This review was collected as part of a promotion.] We have a inflatable pool that came with some pretty lousy repair tape. I tried to repair it, but no dice. I thought to myself..self.. I can use the flex seal! And man, it looks strange, but it is holding up quite well. I have not had the occasion to use this on any hardware or piping in the house as of yet, but I think it will do the trick just fine.

Rated 5 out of 5 by from Amazing! [This review was collected as part of a promotion.] This is a "tool" that you need to make sure you have in your car. I can not say enough things about this. When I was driving, I noticed that my tire was a little flat. Thought nothing of it and went to a gas station to fill it up. NOPE! Not the problem. There was a small leak in the tire and I am so glad I had this stuff in the car. It fixed it up in no item. Really easy to do too.

Rated 5 out of 5 by from Wow! [This review was collected as part of a promotion.] I have had this product for several months and finally got to use it. I sprung a leak in a PVC pipe related to the swimming pool. Low and behold this stuff worked like a charm. You often wonder about heavily advertised products but this really worked for me!

Rated 5 out of 5 by from Not Impressed [This review was collected as part of a promotion.] I got this product to try and use and i had a few places I used it and sprayed and it worked at first but slowly just failed not impressed would not recommend this unless u gonna keep applying it over and over

Rated 5 out of 5 by from Easy to Use and Effective [This review was collected as part of a promotion.] I got Flex Seal to seal up an exterior light fixture that had a support element that developed a crack. I wanted to keep water out of the fixture. Flex Seal sprays on in a reasonably controlled pattern - when holding the can about 8 - 10 inches from the target, it will generate a spray pattern about two inches wide, with minimal overspray - so it is easy to control where it goes. It sprays on a bit unevenly, so more than one coat often will be necessary. The resulting seal seems to work quite well - my lighting fixture has remained dry through several winter storms.

Rated 4 out of 5 by from Inexpensive and works well [This review was collected as part of a promotion.] After seeing several videos about this products effectiveness, I decided to give it a try on a few items. I had a tent, a watering can, and a grill cover that all had developed leaks. I followed the instructions, sometimes built up extra coats, and gave a little extra drying time. All three of the repairs worked well and continue to function. The watering can was the best fix. I applied a thick coating on both the inside and outside of the cab and let it dry overnight. I've been using it for a month since the fix and it's still going strong. The fabric fixes are effective, but the tent has a large black line when viewed from the inside of the tent that can't be changed, just like a fabric patch. I'll eventually replace the tent, but this may get me another few seasons. I would definitely recommend this for a cheap and quick way to avoid replacing a leaky item. It isn't a permanent fix, but it is right up there with duct tape and jb weld. I'll always keep a can around for easy fixes.

Rated 4 out of 5 by from As advertised [This review was collected as part of a promotion.] I’ve seen the commercials on TV and was skeptical. I used it on the inside of my gutter that was leaking, and it stopped the water leak! I haven’t used it anywhere else yet but I’m sure it will get the job done.

Rated 5 out of 5 by from Excellent Sealer [This review was collected as part of a promotion.] After a hurricane, I had a few shingles that blew off the shed roof. Water was dripping inside so I sprayed the Flex Seal as a temporary fix to see if it would slow down. The leak stopped totally. As a precaution I also sprayed on the plywood panel on the inside of the shed and I haven't had any more leaks since using this product. I highly recommend Flex Seal for leaks and will always keep a can on hand.

Rated 4 out of 5 by from Works Great [This review was collected as part of a promotion.] I'm a big fan of the Flex Seal brand. This Flex Seal spray also does not dissapoint. Works great. Just need to watch to make sure you're only applying it where needed. So far no leaks. Will keep purchasing.

Rated 5 out of 5 by from Worked Good [This review was collected as part of a promotion.] I tried this on my gutters and was surprised how well it worked. I was hoping it was seal the seams where they meet and it worked like a charm. It was easy to apply and there was no mess. It dried quickly too. I also used this around my mother in laws leaking skylight in her double wide. I applied 3 coats and waiting about an hour between coats and she's not had any issues with it leaking since. I am impressed with it. I have tried the tape before as well and was pleased with it so was anxious to try the spray and was pleased with it as well.

Rated 5 out of 5 by from Leak was fixed [This review was collected as part of a promotion.] I've used this on a few different projects since receiving it. Worked amazing at sealing a crack that I had in my favorite outdoor birdbath. It was a little messy to use but definitely did the trick. I'm very happy with the outcome on all the projects I've used this for.

Rated 5 out of 5 by from Works As Advertised [This review was collected as part of a promotion.] I had a gutter downspout that came through an upper level deck then turned and ran horizontal under the deck and it was leaking at a connection and dripping on the deck below. I used flex seal to spray the connection and the leak has stopped. Time will tell how long it lasts.

Rated 4 out of 5 by from Great Product [This review was collected as part of a promotion.] I used this product first to seal on a water leakage. it was great and the leakage stopeed. It has to dry a bit to start working. Next time I sprayed it on my plants pot to cover the crack. the plant container was black so this worked like charm. I did not have to color the container with the color. The product is great and works like a charm. I still have to use it on Metal surface to see how it works. but overall the produst is great. I still havent used their other products but now after using this I am very intersted in those,

Rated 5 out of 5 by from Easy to use, works great [This review was collected as part of a promotion.] I used this as a quick fix for a broken gutter. It was much more than a quick fix, this thing is still holding on strong after snow and rain. Absolutely recommend this for all kinds of fixes around the house and more

Rated 5 out of 5 by from Amazing product [This review was collected as part of a promotion.] I’m always skeptical of “as seen on TV” products, but this one breaks the mold for me. You can spray it on pretty much anything and you can coat it with paint. With used it to seal roof penetrations, plumbing penetrations, cracks and walls, etc. It seems to do all those things well.

Rated 5 out of 5 by from This flex seal is awsome [This review was collected as part of a promotion.] I bought this flex seal a month ago and it is like a miracle sealant for just what I needed for my leak in my windshield on my car windshield! This Flex seal is like magic! And I can't wait to buy another one real soon!
