I'm repairing a ding to my rear bumper and I plan to prime and repaint the whole bumper. I'm hoping that someone here can point me to the paint code / formula that is an exact match to the original color. I have seen some suggest that Rust-Oleum 302590 Chalked Charcoal/Gray is a close match. It's true, it's quite close, but it's not exact. Since I'm going to be replacing the plastic fenders too, I'm really set on having an exact match. Does anyone know the original paint code / formula?
