Correct Grill Color

Your best bet would be to strip the black paint off first, if you don't, any chips you get from road debris will show black paint thru. You can do this with oven cleaner, it wont hurt the plastic, spary it on, let it soak in, wash and scrubb off. The rallye wheel paint is a close match from Mopar, it is very durable and will hold up nice to rock chips and road debris. Otherwise, get some darker/argent silver at a local parts store.
