Except that there was no actual water damage. I've bought some of that 3M material for some research experiments and it really shouldn't be used the way it is in electronics. It can turn red in humid environments. They're best used with things that are IPS rated like Pelican boxes, to assure rain isn't getting into them in an outdoor environment.
