OK fags. /b/tard here.
Prepare to science for me.
Have this nice aluminum cake pan for use as an outdoor kittywater repository.
Started using it in late Spring.
Some months later noticed these smallish pits in the interior.
Does anyone know if this is normal for this type of aluminum exposed constantly to water and much direct sunlight?
If these pits are not the result of "normal", expected oxydation/breakdown, then my thoughts for an explanation would be:
a. Contact with some type of noxious or corrosive particles that blew into the water and settled there (WTF could that be in a residential suburb FFS?).
b. Damage from cosmic rays.
WHAT SAY YOU, /SCIENCE/?
