I have developed an issue with my '08 sti bbs wheels. I have rust on the metal ring where the lug nuts seat the wheels. I had been using p21s wheel cleaner up until last year when I switched to sonax, not sure if this had anything to do with it? Anyway, I pulled the wheels off and spent a few hours yesterday with lime away and removed all of the rust, unfortunately, today I noticed that the rust is starting to return already. Does anyone have any suggestions on how to fix this?
