Flex SealÂ® is now available in White, Brown, Almond, Silver, Green, Blue, Red, Terra-Cotta, and Yellow!
Since the first success with flex seal I used it to repair some other things. I fixed a garden hose, an old metal bucket and a window that was leaking cold air. When the flex seal is dry you can paint it if you want. I didnât paint my roof because itâs black and flex seal was invisible.
