Painting

If the hood is painted in a black like this, is the underside also black or is it body color?

I painted some parts before and used the flattening agent with the clear - it still came out mighty glossy. I will have to try and remember what part it was, but I think we used a 50-50 mix of clear to flattening agent.

If you used a trim or satin black only, can it be waxed?
