I used the Flex Seal in a spray can on the shower skylight in my last class c. It did not hold up and did nothing to stop the leak I was experiencing. Scraping all the old dicor off and cleaning the area and then applying new dicor stopped the leak. The one thing I know is if it's sold on TV it is a gimmick. You never see anyone winning a fishing tournament with a pocket fisherman.
