    Weird outer shell markings/corrosion (?) on polymer caps







    Just saw this on another forum. On some caps it looks like a plastic coating is peeling/falling apart.

    Does anyone knows what's up with those caps?

          The microscopic fungus(?) that eats aluminum like they found eating away at CDs not so long ago?

            Looks like some kind of insect damage, The aluminum is not touched, it is just the coating that is being eaten.
