    Flex Seal Liquid

    This stuff explodes!

    Overall Experience:

    I was using Flex Seal when the whole thing exploded! I spent one month in the Burn Hospital in Phoenix. This stuff can be very dangerous!

    I had used Flex Seal two weeks prior to the explosion with no problem in the exact same spot that the second can exploded.

    Apparently, Flex Seal has a very volatile propellant. There were no open flames near me nor anywhere close to the space I sprayed. I've read online that people had Flex Seal explode while spraying outdoors on their roof.

    Do not use this product unless you completely wrap your self in flame proof clothing. Including protecting your face.

    Bottom Line: No, I would not recommend this to a friend
