How to paint engine bay?

Hard to justify not going body color.... Napa did my mix into spray cans like I said above. My engine bay was clean but I wanted to touch up some scratches. Seriously... You can't even tell I hit it with a spray bomb. Best part is... I have 4 extra cans of color matched paint left over to use when needed.

I have touches up some trunk floor scratches and fogged over the rock chips on my front, lower valance. I can't even tell so I know others will never notice.
