My first thought was something thrown up from a belt but then the spots would not be nice and round like that. Anything thrown from a high speed rotating shaft, belt, etc would create lines or oblong marks.
That is why I asked the rust proof question as this looks very nicely sprayed from a short distance away with a low pressure source. There may have been a very slight back to front angle as the top spots are a little more spaced out then the bottom but there are still spots away from the central pattern on the bottom.
THIS IS GOING TO KEEP ME AWAKE AT NIGHT!

Only spot is there, and a couple dots on the back end of the hood. I don't see any drips, but it's hard to put cardboard under the car as I live in an apartment complex.

Nope, I have my second key.

They feel sticky. Can't smell an odor either. This is weird.

I think I noticed the exact same dots under my hood during my last track day.

Were they located towards the battery, near the passenger side firewall?

Nope, these are on the driver side. The passenger side is clean of any spots.

Is your oil filter on tight? See any liquids in the area under the hood where it could be coming from? I would look directly below where the spot is on the hood and check as there has to be some evidence of where it's coming from since you say it comes back if you clean it.

Ok I will check my car when I get home. I thought I remembered seeing them on the passenger side.

Never thought about the oil filter. But what's directly below is an AC line, and 4 other hoses. I'll take a pic later when I get home.
