Dear flex seal, 5/4/2020 I writing to let you know of a problem I have just discovered with a can of your spray-on flex seal. Three weeks ago, I built a new large storage shelving unite in my garage and collected all my spray cans and loaded the shelves with them. Along with all my cans was a new can of your flex seal. Two days ago, I went to the garage to use the flex seal and found that the spray can of flex seal had apparently exploded and covered the shelves and the floor with a brown sticky liquid. I left the can just where I found it to show you that the plastic top of the can shattered when the can exploded. I have all the pictures you might like to see and thought you might like to comment on what has happened. Leslie r. Phalen
