Stuff Really Works
I bought some Flex Tape as part of some random supplies to go on a trip because I'm the type of guy that overpacks tools and accessories hoping that I will never need them, but knows that it's possible that I might. Well I was out on the lake with my deck boat and ended up getting a bad small that seemed like it was coming from my outdrive. I unscrewed the dip stick to check the oil and realized that the dip stick threads were completely stripped (the top of the outdrive is above the water line when not in motion). There didn't turn out to be any issue with the oil, but now I was stuck with a dick stick that was no longer water-tight that has to be in the water. I wasn't in a place that had a good cell signal and had to get back to the marina, so I used some Flex Seal around the head and then used Flex Tape over the whole dip stick and port and ran my way back in. I was very pleasantly surprised to see that no water penetrated the Flex Tape, what looks like moisture inside is Flex Seal that I kind of got all over the place. With a boat running on choppy water and relatively decent speeds, this product held up and didn't allow water to get into my outdrive's oil. This product is very flexible and pretty easy to apply. Try not to let the adhesive side roll up on itself or you're going to have a problem trying to get it to pull apart again. Once the product is applied, that same piece cannot be pulled off and reapplied. It's a very strong seal and if you need to get it off it takes some will-power. I used a drill with a drill-eraser to get it all off.

"CLEAR" Tape Turns YELLOW in POOL
I paid over fourteen dollars thinking this tape would be CLEAR as it states on the package. However, a few days laters, I now have YELLOW TAPE in a few places on the liner of my pool and it looks TERRIBLE. If I'd known it wold TURN YELLOW, I would NOT have purchased this tape.

    I got hosed for $20
    I have acquired multiple high-quality garden hoses over the years. Unfortunately many of them have developed small pinholes in them. I was advised by the HD staff to use this product so I bought the big roll since i have several. I thoroughly cleaned and dried the surface of where it was going. I followed all the directions. I was very excited to fix this first hose with it. Unfortunately as you can see from the photo it didn’t work

        Incredible product!
        This is the first waterproof tape I've used that's actually waterproof! Our 4 foot vinyl pool sprang a leak on the side wall. Brand new pool, very upsetting. I read how this tape will seal even on wet surfaces. I'm thinking yeah right. With water streaming out of the hole in pool, I applied about a 4 inch piece over the spouting hole. I smoothed it out to get all the water out from under the tape. And to my amazement it stopped the leak!

          Doesn't last. A waste of money.
          We used this tape on our pool enclosure screen and it only lasted 4 months. The glue on the tape dried up and cracked off. For almost $13 for a 5 foot piece of tape this tape should work. Don't waste your money.

            I have a 10x20 tarp enclosure facing it's second winter. I noticed a seam split at the front peak, and quickly sealed it using Flex Seal Tape. It did a great job, the split has been sealed, and I should be able to make it past snow season. I ordered a replacement roof tarp, so I know that my temporary fix only has to get me past the snow season, and the Flex Seal has prevented the tear from expanding and getting worse. I visually inspect the split each day and so far, the tape is holding. I have to give them credit where credit is due, and this has been an impressive product for me, much better than I could have expected. Well done Flex Seal, keep up the good work!

              Fixed 3 holes in my 14 ft intex setup pool while it still had water! Worked perfectly just make sure you aim straight for the leak and step down to put pressure and flatten the tape out! No more leaks! Just wish my husband bought the clear one instead but alas it’s just a pool.

                Definitely will not work on a garden hose.
                My garden hose had a small leak from a cut and I was hoping it would stop this little hole. The instructions do read that not for high pressure and it for temporary fixes, not permanent. So what is high pressure and I had to buy it anyway to test the product anyway. Another reviewer tried it on a CPVC pipe inside his home and the same no go performance. I stops the spraying but water trickles out from under. The bottom line is the water pressure has to be behind it, such as in a pool where the water pressure pushes against it to help seal it off. Otherwise it does appear to be a good product for other uses.

                  I used this (FlexSeal Liquid) on my porch's barrel style metal roof, circa 1939. I was tired of paint (even paint designed for hot surfaces) peeling over the years. The real test is will this product endure the Florida sun and heat. So, far (a few months) so good. This tape was used on a small hole that rusted through on the drip edge.

                  The product is holding up so far on an outdoor bin that had cracks in the lid. I'm anxious to see how the tape works after a few months or better! Only issue I have had was cutting the tape with a scissors; kept sticking to the blades and was difficult to get the residue off. I've had the product for about 3 weeks so far.

                      Strong adhesive tape
                      [This review was collected as part of a promotion.] I used the Flex Tape in my bathroom to reinforce the seal around my bathtub. The tape that was there was peeling off and needed to be repaired. The tape works excellent, the bonding surface should be dry prior to applying the tape. I used the extra wide tape which was slightly too big so I trimmed to the size I needed. There have been no leaks so far and the seal is tight and waterproof. I am definitely picking up some more for some other repairs around the house. Flex tape is a super strong adhesive tape that has a rubberized backing, works underwater and instantly stops leaks. I highly recommend flex tape for sealing out water, air and moisture leaks.

                          Heavy duty seal
                          [This review was collected as part of a promotion.] I am in absolute shock in how well this tape works. I was skeptical at first to try this product out on our cracked window in the middle of winter with rain and snow outside with freezing temperatures, but my wife insisted we try it anyways. I thought for sure we were going to have to replace our window, but much to my amazement, this tape has sealed and held up despite these extreme weather conditions. It truly does have a super strong adhesive backing and holds up well. I love that it is 8 inches wide which allowed us plenty of room to cover the entire crack on our window. It definitely is waterproof and has not allowed any moisture to come through on the tape or around our window where the tape is placed. It has not peeled up around the edges and has bonded strongly to the glass surface as well as the wood frame of the window. I would definitely recommend this to others who are looking for a strong adhesive, waterproof, get the job done, without the worry, tape.

                            This Stuff is AMAZING!!
                            [This review was collected as part of a promotion.] I figured I would get a roll of Flex Seal tape just to see if all the hype was true. As an engineer, I wanted to see if it would really work. Having played with duct tape for years to do repair and knowing its limitations, was this tape really better? Bottom line, YES it is!! I had a chance to use it on a repair for my water hose that was going bad. I opened the package and unrolled a piece of tape, the first thing I noticed was the tape itself was very thick and made of a rubberized material, like a pool liner. The material is very pliable and will mold itself around any curved or odd shape. To cut it, you need a good pair of scissors, there is no tearing this tape. The second thing I noticed, is the glue used on the tape is unbelievable. Once taped to something, especially to itself, its virtually impossible to take off with out cutting it off. The first time I wrapped it around the hose, it was a little uneven, I needed to cut it off to do it a second time. Once I reapplied the tape the hose worked like new. There are a few tools that every house needs, hammer, screw driver, etc… Everyone needs to add roll of Flex Seal tape. The number of applications for this tape is endless, the quick temporary patching of holes in walls, to stopping leaks in pipe or hoses, to things I can’t think of yet but will have Flex Tape for it just in case. I would highly recommend have some on hand just in case and give it as a gift, they may look at you strange, but they will definitely thank you the first time they need it.

                              [This review was collected as part of a promotion.] I noticed my floor damaged from water and being scratched from a potted plant. I did not want to repot the plant, so I used Flex Tape on the bottom. Not only did it stop, the little leak but, it protected the floor when I slide the plant. Flex Tape is easy to use and cut. I like the 8" x 5 " size, it makes a project like that easy. I am happy to have this in the house, you never know when you will have a leak. It is good stuff and I highly recommend it.

                                [This review was collected as part of a promotion.] Beware this tape is super sticky. Don’t try dealing with it in the wind as I tried using a cut long strip to patch a tear in my swing awning and the wind folded the piece onto itself to where it was permanently stuck. I used a different piece and it worked as advertised to fix my torn awning. I will see if it holds through the weather but so far I’m impressed. I look forward to using this tape in other situations around my house.

This could help those broken stuffs at home to be fixed plus it is waterproof! It is mess free unlike those that creams that needs to be mixed thoroughly but with this, it is easy breezy. But I hope they also comes in small sizes because it is easy to roll it in a small things that needs to be repaired.

                                    Decent Product But Difficult to Use
                                    [This review was collected as part of a promotion.] I was excited about Flex Tape and being able to use it to cover up a hole in the siding of my house. In fact, it seems to be working well on that patched hole. Here’s what I liked about Flex Tape. It’s wide. It’s 8” so it will work well in patching larger holes. It works in hot or cold temps. It even says it works underwater! It’s flexible so it works on odd shaped surfaces. Speaking of surfaces, it says it works on almost any surface, even brick. I like that the Flex Tape is available in Clear, White and Black making it blend with multiple surfaces. While I like some of what Flex Tape offers, I had a HUGE problem with how difficult I felt the tape was to work with. The instructions literally say “Just cut, Peel, Stick & Seal” It sounds so easy doesn’t it? It was a pain in the behind. With it being super sticky cutting is almost impossible. The first try it was so jagged and crooked and sticking to itself I had to toss the piece out once I finally got it cut. For the second attempt, I had to get my wife to help me pull and cut the tape so I could hold the other end tightly with hopes of an easier cut. She cut the piece and it went a little smoother as she slid scissors across it like a razor blade instead of using a cutting motion, which is suggested on the instructions. It wasn’t perfect but did work better. Once it was cut, it folded over and stuck to itself before I could get it into place leaving it useless. Finally, on the third attempt I was able to get a piece of tape I could use. While doing all of this cutting, the plastic backing, which should help you separated so easily from the Flex Tape, I found it to only hurt my efforts. In the end I was able to cover the hole in the siding as I had hoped. It stuck well to the siding and covered the hole completely. The Flex Tape packing says the bond only strengthens with time so I expect this to hold until I can get the piece of siding replaced. I do recommend this product but I do so with caution. A product like this should be easy to use and not frustrating. After all the trouble in using this product I would look at other options as well before choosing this again to make sure I was getting a product that is easy to use as well as one that works well.

                                      I purchased this Flex tape 4 inches wide X 5 feet long, to use on my water truck for work which is leaking water. It really needs a new tank. So I cleaned the area with a wire wheel first. Then I cut the tape which is really sticky and hard to let go of. I overlapped several pieces in multible areas. So far it is much better on the leaking. I don't leave a lake everywhere I stop.

                                      Interesting application, but frankly, it just works. This stuff just plain STICKS! And I mean, sticks. Not the easiest product to work with but it seals, applies well and I would anticipate it lasting a long, very long, while. The glue is difficult to work with but that is because it applies strong, sticks and seals due to its thickness which allows it to seal so well. I will always keep a sheet of this around for the times when a seal is needed now, not when a repair can be made based on someone else's schedule. This is a must have around the house, it will come in handy and possibly save you a great expense for a situation that took too long to address. My only criticism is there are no "clean up" instructions. Lighter fluid, alcohol or mineral spirits will do the trick, but that is not addressed in the instructions.
