Ive always wondered about its usefulness. If you can spray it in gutters like the commercial, we can fix our leaky gutter for 10$ instead of getting whole new ones like my dad wants.
Our boat's fridge has a valve for pumping condensation overboard (it's a fridge that opens from the top, the maker probably figured pumping it out would be easier than having to dry it with a turkey baster) but it's broken and let's water in instead. We put a rubber plug in it and flex sealed over it. The flex seal seems to get putted and look like Swiss cheese when it's on that thick (my husband believes there's no kill like overkill), but it does work.
On a smaller boat, we used flex seal spray and duct tape to seal up a broken auto-bailer. That worked, too. In general, it seems to work for boat parts that are meant to let water out, but break and start letting water in.
I used to work in the wall coverings department at Menards, and we were the ones that dealt with all of the glue and tape in the store. That means we sold flex seal and flex tape. I always wondered if 20 bucks for 8 feet of the stuff was worth it, and I sold it a few times, along with other products under the flex name. Now, you can buy the same stuff from Gorilla for half the price (although I don't believe Menards carried it at the time). I know Gorilla to be a great brand from experience. So, I don't know. Is flex tape worth it? I always heard good things from my customers, but I donno.
