The backside of your wheels should be Black. Some will say Gloss others will say Semi-Gloss. The front should be sprayed with Argent without any rear masking so as whatever Argent blows back there is correct. I like Totally Auto's Argent in a spray can for easy of use. Also Mopar Performance sells an Argent Wheel paint also. Don't have a formula if your spraying in a gun.
