I followed the instructions carefully.

I sprayed the inside of the gutter - and it still leaked - sprayed the outside around the seal 2 times and it still leaks.

It wasn't cheap in cost either, so I would hate for anyone to waste their money trying it.

Go to Home Depot and buy Rustoleum Leak Seal for $10. same thing, no hype, trusted company, no extravagant handling charges. For bigger cracks use Rust-Oleum 5091 10-Ounce Tube Watertite Poly Seal Joint Filling Waterproofing Caulking first.

I used this to patch an asphalt roof leak around a sky-light. I followed the instructions carefully. Frequently shaking and holding the can upside sown to clear the nozzle. I ran out of propellent while there was still product in the can. I used one can then waited a day to apply another coat with the other can. No rain and low humidity between applications. I applied a six-inch wide patch with one inch up the side of the sky light. Coverage I got out of the can was about eight square feet per can. Next rainfall, I still have the leak. I can't imagine applying the product any thicker. I would say the product is over priced and in-effective.

I had some flashing around my chimney and some gutters that were leaking. The roofer told me he needed to replace and reseal the aluminum flashing (although it showed no wear at all) an replace all of the gutters. The job was going to run close to $600. I'm on SS and knew I couldn't possibly afford that but a friend suggested I give Flex Seal a try. They sell it at my local grocery so I picked up a couple of cans for about what they go for here. I'm glad I did. I cleaned up all the areas and liberally sprayed the stuff. That was almost two years ago and I still have no leaks.

I used this product on my gutters where one of the joints were leaking. I read and followed the directions on the label and was impressed when I sprayed it on. A few days later we had a light snow storm but when the snow melted the joint was still leaking. Ok, I removed all the rubber from the joint and cleaned it thoroughly then applied Flex Seal for a second time. Again, a few days later we had moisture and the joint still leaked. I have since applied caulking and the leak has stopped. I tried it on another application in which water leaking is an issue and it didn't work on that either. I am impressed with the "spray rubber" concept but it didn't work as advertised for me. I would not recommend this product.

I used the product on 2 different items and it did not solve my problem in either case. It is very messy and if it gets on your clothing kiss it goodbye. It was a big disappointment and I followed their instructions very closely.

Do not pay these foolish prices for this stuff. This is just Rubberized undercoating in an aerosol can which can be purchased at any auto parts store for around $5. I can't believe these clowns can get away with charging so much for this.
