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.

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

Nozzle broke after one use: good seller though
The nozzle stopped working after one use. It’s in max opening and I’m holding it at the right angle. The first use it came out good but it is hard to clean if you get it where you don’t want it. I used my finger to spread it out and it was so sticky on my hands and soap and water didn’t even get it off. I had to use a baby wipe. I’m not sure how long it will last on the sink but I'm disappointed for that money I only got one use out of it since the nozzle broke.Updated review: increased stars because the seller was attentive and refunded my money. Maybe mine was just defective.

Easy to use.
Easy to use. Needed to seal a baseboard in a wet area. Application was easy and so far is holding up very well.

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
