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

Worked well for some front porch railings aluminum spindles. Be sure to clean the surface first and have a rag handy for any residue.

keep rags with you, it can be messy until it sets.

have a couple rags with you, it can be messy, but wipes up easily while fresh, might be harder to clean up after it sets, but I won't have to worry about leaks, water won't get passed it.

Easy Even for a Mechanical Disaster Like Me

I am a walking, talking mechanical disaster, and even I couldn't screw up this. It is so amazingly easy and works beautifully.

Not as expected

Per instructions, I attempted to slowly apply the content but it was by no means coming out as a continuing flow. It was in lumps no matter what I did, the end result to seal the leaking window allowed more rain than normal into our solarium. Today, I will use Gorilla Tape to seal the window, not what I wanted but the water is damaging the wood and our Spanish Tile. Very disappointed

Love FlexSeal

I should be a spokesman for Flex Seal. I always have everything they make in all of the colors on stock and when running low I stock up like I just did. This stuff is amazing. I know from using at my home, our camper our sheds just how well this really works. I have told so many people about this they all stock up as well. A few years ago a tree branch came down thru my shed roof. We had to cut the branch just to get it out of our shed. Well I grabbed my ladder, Flexseal tape and spray and went to town. 2 years later it is still holding well. I can't say enough

Overall works well but required reapply

Sealed the small leaving spot in tub for dog washing. Works well but will peel out after a period of time and will need to be redone
