I have a nice thumb tack sized chip around the arch of my driverside rear wheel opening. Want to get it just touched up until I have the few spots professionally done. Has anyone found a close color match for the 18U Magnetic Grey Metallic/Evoke Grey that I can quickly get just to cover it. Everyone around here is special order or not available and I dont want to spend to have a custom made color bottle, I will ask for that when the car cleaned up by the body shop
