The factory grill was painted by a robot. The flat black was sprayed after the argent silver was painted or dipped. The grille is argent under the stainless bars. They were installed before the black was sprayed. The back of the grille is argent also. The only Impala to get the bars were SS427 cars. To spray the black is a job. You will have to tape each bar so the argent is not sprayed. NICK L72
