Works just as advertised. I used it to seal a large/long area in the bow of my 14' aluminum boat. It was easy to apply and doesn't take long to set up and cure. I'd recommend it!

This Product totally works, just make sure you use a few coats and don't just load it on all at once or only use 1 coat. USE A FEW GOOD COATS and it will seal the leak. I purchased a pre-formed pond that had a crack & it looked like they tried to seal before but still had slight leakage. I removed all previous glues & just sprayed a few coats of this flex seal and the pond no longer leaks at all, completely sealed it up.

I had a small leak between roof panels over enclosed lanai. I sprayed the seam in the hot sun yesterday and 6 hours later it rained 1.5 inches and I am happy to report, not a drop of rain came thru. The product did the job it claimed and was far less messy than using elastomeric spreads.. Michael, Spring Hill FL.
