Black spots on my weight rings???

I recently bought a yyj New Breed and it was the last of the colorway made. I was very excited until i realized there were large, obvious black spots on the weight rings. when i tried to scrub them off with a cloth they didnt budge. Does anyone have a clue what they are or if they are supposed to be there?

Post some pics so we can see what you are talking about.

Sounds like it might be some oxidation on the rims. They are raw aluminum so they would be susceptible to he elements.

Definitely sounds like oxidation so you’ll probly need to look up the polishing guide
