I have just bought a Challenger T/A 392, with the matte hood paint finish and matte overlay top and trunk lid. I also believe the spoiler and front lower air dam are matte finish. I have been told not to use normal car care products. Is there a single product that can be used to wash and wax both the matte surfaces and the regular paint? Or do you have to use one product on the matte finish and another on the normal paint?
