What’s wrong with it?
The contents of the cans can react with the package, causing rust to form along the can seam, which could spread to other areas of the can and create pinhole leaks. Leaking propellant poses a fire hazard when it comes into contact with sources of ignition. Leaking sealer can also result in property damage.
