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? |

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