Hubcap restoration

[budnate]

they are stainless...but they have some kind of finish on them...I have accidently wet sanded through a couple trying to smooth out a rock nick...then they have this real grey look almost like steel..

I tried to hand polish the spots but it did not help, I did not jump on a polishing wheel with them...

like I said total amateur on this end but have saved about 10 of them with a 350 balancer and a small ballpeen hammer....

I think they were flashed with something like the valve covers...turn them over and you will see the grey finish I am talking about...are yours "Canada" stamped caps???
