Holes in aluminum body?

[tubeexperience]

A relative brought to me a 13-inch MacBook Pro.

Anyway, on the aluminum where the hands would rest, there are a bunch of holes.

It look like someone took very tiny drill bits and drill holes into the aluminum, except that holes are irregular shape. WTF?

Previous owner was a xenomorph hybrid with acid for sweat.

It likely pitting from the previous owners sweat, just google it and you can see many cases.

Wow, that's so weird. My personal MBP doesn't seem to have this issue.

Very specific issue that's caused by the individual. I personally don't have this issue but my brother for example does.

Relatively normal. My old 2006 MBP armrest looked like a swiss cheese after 8 years of use.

Solution: Use an underlay or stop sweating.
