Works as Advertised

I used it to convert a couple tube type motorcycle rims to tubeless. The Flex Seal worked great. Great adhesion, thick and strong and pliable.

A LITTLE MORE EXPENSIVE, BUT IT WORKS WELL... NOT REALLY BLACK

A little more pricy than at the big orange box store, but by the time you drive there and put up with all the BS, it's not that more expensive. I've always had good luck with Flex Seal until the lid doesn't seal properly anymore and half the can goes to waste. To prevent this, I line the top of the can with painters tape so than none of the product drips into the lid seal ridge and then throw the tape away when I'm done.Also, this stuff doesn't really dry black, more like a dark grey. Which may, or may not, be an issue depending on what it's being used for.

Amazing

So I used this to redo my rv shower pan works great. The only reason it didn't get 5 stars is now my shower is slick as ice when wet and no footy grip pads will stick to the floor.

Best solution for a flawed roof design

My patio roof mounts directly to a wall, I have fought leaks for years, tried patching with both caulk and silicone, which tends to leak over time. Time to try Flex Seal, after cleaning the area removing loose caulk and dirt, I followed directions and with a 2” brush was able to work Flex Seal into small cracks and crevices while building a smooth outer finish to deflect water. WOW Flex Seal works as advertised, the consistency of the product stayed the same which made applying much easier.PROS: easy to apply, adaptable to contours, spreads evenly leaving a smooth surface, adheres wellCONS: none for this applicationAdvice: Stir contents well before using, wear work clothes

Flex Seal For Driveways

I used Flex Seal to fill cracks in my drive way. It applies easily and levels perfectly. I have used it for 3 seasonal years to since I found Flex Seal. The cracks are still covered. My driveway is 14 years old, so the spider way cracks are my concern at this point. I was spending an outside sealing company to my sealing every year and cracks always reappear the filling year. The only reason to use them now is just for the curve appeal, when needed.

Works as advertized - Good stuff

This roll-on (or paint on) works much better than the spray on, depending on the job. Make sure you buy just enough for the job. Does not store well once opened and exposed to the air, and it's too pricey to throw half a can away. One month maybe two at best storing it. I use it on my 5th wheel for several diff applications. Wear rubber gloves because it is messy. If it drips on floor or wherever you don't want it, LET IT CURE before picking it off. If you try to wipe it up while is still wet, it smears all over the place. Once you open the can, DON'T dally. It starts to skin over PDQ. Good product

It Worked for My Specific Purpose

I bought a long "garden bench" (shaped like a panther) to place along a diminishing step-down so I would not trip and break the other hip. Unfortunately, it did not do well in rain, so my "fix" was to paint it with Flex Seal and then spray paint it with its original color. It worked for me, and was reasonably priced. I rated it "3" on Durability only because I don't know that yet and figured 3 = average; otherwise it is five-star.
