Black engine bay's?

Take the time to paint it body color, even if its mixed and put in a rattle can by a paint shop. It will lose its lustre over time but will still look nice as you dont need UV protection under the hood, a better solution for only a little more money is single stage acrylic enamel, it is 15X tougher than any 1k rattle can mix, as it is catalized, and will hold a beautiful shine indefinately under the hood...it is cheap and well worth the money spent imho.
