Works perfectly!

Flex Seal allowed me to fix the galvanized tubs that we use for drinks. It sealed any of the openings that have happened throughout our use. Now I can continue to use them without any leaking.The directions on the canister are super easy to use. The product dried to the touch in like 20 minutes and then was dry for use within 24 hours.I didn't notice a smell while using it. Also know that the caulk is white, so you may have to paint over it.

only for small projects

Product was good. Comes in handy for a small project. It won't let me control the amount of caulk, only comes out in the 'max' position. A lot is wasted and the small tube runs out fast. I personally prefer to invest in a good caulking gun with a regular tube of caulk.

Nice & Easy

I watched the video before buying. (I am elderly handicapped.) I bought one of these last year to seal cracks around an exterior window from the inside. I used the whole can to go around the entire single window. I have never used caulk before, but this was simple and not messy. I noticed some cracks in old caulk around other windows this spring and bought some more for them. Wonderful.

Great product

This was exactly what I was looking for. A little expensive and came out a little fast at first but got it figured out and worked great.

Easy to use but turned yellow

At first I really loved this because of how easy it was to use. However, after a month or so the clear I have on my white shower pan has now turned yellowish. I’ve cleaned and sprayed thinking it was just dirty… but nope.

An Amazing Product worth Every Penny

Where has this been all or my life! Worth every single penny. Flex seal is a product I have used and trusted for years, so I was SO happy that it came in an easy to use tube. It was so seamless to use, and the leak I needed to seal under my sink was done in less than 15 mins. I saved myself $150 in a plumber (which I had already called out 3x in the last few years and all of them never remedies the issue by using cheap caulking that doesn't last.)

FlexSeal Promised a Refund - NOPE!

I purchased 2 cans of FlexSeal to touch up a few areas in the kitchen and bath that had begun to erode. What a big mistake I’ve caulked before but I couldn’t find my caulk gun after a recent move. FlexSeal seemed ideal! No caulk gun needed. Based on the commercials and online videos, it seemed simple to use. NOPE!I was contacted by FlexSeal following my initial review. A representative said that I would receive a refund for one of the cans I purchased. After a month, I followed up with a call. Then I made another call and another call. Each time I left a message. To date, I never received a call back or that refund check. Save yourself some aggravation and don’t buy! Please read my original post.FlexSeal does not come out in a nice small bead. Even on the lowest setting, it spews out in a glob. It is sticky and adheres to surfaces almost immediately. You cannot use a caulk tool or your finger in order to get a tight seal because FlexSeal sticks to the tool and you. Here is the good part soap and water is pretty much useless against FlexSeal. You will need acetone or mineral spirits to get it off you and unwanted surfaces! I nearly scrubbed my hands raw trying to get it off me. Ladies, it will also eat away and discolor your nail polish!I made a mess in my kitchen on the backsplash and granite. A simple maintenance job with an inferior product is now costing extra money. I’ve nowhired a handyman to tackle the FlexSeal mess and I’m stuck with an extra tube of the stuff. I only used the white tube and cannot return the clear. Amazon will not take it back!! They know this product doesn’t live up to the hype. I should’ve just bought a new caulk gun and regular caulk, and saved myself some money and aggravation.
