I am attempting to do some touch up on the front bumper of my car, the paint WAS perfect before ><

Trying to match the paint code off RPO codes I have WA- L0848 U0848.

Those both point me to black but the car is a z28.. upper black lower silver with a red stripe.

Does anyone know what paint I could get in a dupli-color or some such that will match the lower flares?

All I had was a gif of the car so that's what I uploaded
