Great seal

a year ago
I got this product for free from influenster and Flex Seal in exchange for my honest review. I didn't think this would work well because of the cheesy commercials but once I was able to get the nozzle working it worked great and was easy to use. I dislike using a caulking gun and with this one I can go without one. I not a fan of the price tag but if it saves me time and money in the long run than it's OK for me. I would recommend this to anyone that isn't a a fan of the caulking gun.

I will stick with OG

Black caulk and white was interesting to use. It doesn't get hard like regular caulking. It's made out of some kind of rubbery material. I like the easy squeeze applicator. However, I was not a fan of that texture left after dried. It worked best for very small holes from picture frames . Anything bigger then that turned out really weird. I haven't got to paint yet. However, the packaging says you can paint over top of the caulking. My husband is a contractor. He prefers regular old-school caulking. If this company could provide that with the easy squeeze tube, I would give it a 10 out of 10.
