Flex Seal LiquidLarge 128 Ounce (Clear)

Worked great on my leaky gutter . Brushed it on with amazing ease . I admit I was skeptical but 2 days later it rained pretty hard and not a single drop leaked through ! Wow ! Highly recommend. J. Santiago

The product works ok, but it's too shiney for many jobs.

Used the flex seal to coat the inside of my swamp cooler so the metal wouldn’t rust in the hard Vegas water.It worked great and has held up for years now

I like flex seal, I just wish the can had been bigger. It does say 16 oz. on ad but it shows man with bigger can too. It's a little deceptive having the bigger cans in advertisement for this smaller can. But the product is as it states it is. It does work very well. I used it on a cement birdbath that had some cracks in it, and it does not leak now.

Can was dented when it arrived. Does not brush on very well. Tried to use it on 3/4" treated ply wood, put 2 coats on, allowed a few days to setup. peeled right off using just my finger nails. Won't buy it again.

it was much smaller than expected...can get this plus caulking on their tv ad not only didn't save money but didn't get as much as another offer!!

Product is easy to apply and I am assuming will work great, just like in the commercials. However, the can arrived banged up and dented! The handle was no longer affixed and it appeared to have merely been tossed into the box. There was very little padding (a few of those puff pillows) and the bottom was so dented that it could have easily leaked. Someone needs to talk to their packaging and shipping department and refine their quality control of how to properly transport this.

Pretty solid product but not perfect.
