I have a 2009 civic Si. I want to polish the face of the rims so that they are mirror finish or close to it. The rims are mint and are currently on my car. I was going to try Meguiars Hot rim mag andaluminum polish to see if this will get me what I want. The rims again are MINT. I'm skeptical about sanding them down first then polish... Maybe with a 1500grit wet sand? Or JUSt the polish?
