Flex Caulk, Waterproof & Weatherproof Hybrid Polymer Sealant, Strong, Paintable, Indoor, Outdoor, Bath, Shower, Sink, Window, Baseboards, Door, RV, Roof, Wood, Auto & Marine, White, 9 oz, 1-Pack

Good stuff, really like the trigger control, a little bit of a learning curve to applying to right amount of pressure to the trigger for the amount you what to use.

I certainly have used caulk guns many times, but I was working in a tight space. This made it easy! If your space is even tighter, you might buy the 3-ounce tube, but it is very expensive per ounce. I got the 9-ounce tube of the hybrid polymer. Which is still expensive per ounce compared to standard tubes. But the easy trigger makes it worth the money, especially when working in difficult places. There are advantages and disadvantages between silicone and polymer. For my application, polymer is much superior. But polymer is NOT water cleanup. That is not the product's fault, it is the nature of polymer sealant. You just need to know that. I did use my finger with it, and it isn't easy to get off but that is something I understood. I guess the only complaint I have with the spray can is that you can't tell how much you have left of the product. You just use it until it runs out. But the 9-ounce tube completed my project. One user complained that it was difficult to control the size of the bead even with the adjuster. I didn't have that problem, it came out great for me.

This product is very easy to apply. It is not messy at all and doesn't have an odor.

The container is brilliant. I wish more companies would do this. However, clean up is not easy like others caulks. Very hard to smooth.

Great product

It was very easy to use and it has worked perfectly

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 now hired 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.

Didn’t spread very easily, came out in blobs

I did want to return it as it doesn’t live up to the hype. Caulking mixture goes everywhere and it’s hard to remove to clean it up. I did also buy Flex Paste and when opened it was rock hard. I was able to get a refund on this one. Expensive rubbish
