My grill (stock) is argent silver, typical silver trim color for a Camaro. You should clean the grill of all crud, grease, and boogers. I used a scuff pad to just clean mine up and get little boogers off the plastic. After that, I taped of the body color area and stainless trim then shot it with PPG base and clear. I like the clear for the ease of future cleaning. We flattened the shine of the clear abit so it looks right.
