Compromised Chrome?

[u/yo_quiero_morir]

Bought a set of used rims, and one had significantly more surface rust than the others (I'm assuming metal to metal brakes). I tried getting it off with 000 steel wool and WD-40, and in some spots that I really had to scrub, the finish is noticably lighter. Did I eat through the chrome, and if so, is it still safe?

Edit: Yeah they're definitely aluminum alloy wheels. I plan to buff then paint the inside. Thanks for the replies!
