The inner fenders are semi flat black. Very easy to touch up and pretty durable too. The radiator support I made is just PPG black base coat/ clear coat. I tried to make it look like a factory install. So most people don't realize that the firewall has been smoothed and I plug welded and smoothed all the holes in the inner fender wells. The best part is that most people don't see that I welded and smoothed the subframe and moved the front shock mounts up 1 3/4" so the car could sit lower and still have a full length shock under it. That took forever.
