Agreed, I like my car clean under the hood.
My good friend could have done with a belly pan when he drove from BC to Alaska on the Alaska highway in the mid sixties. When he got back his car was wrecked and you could see nothing but dust under the hood, dust piled on everything. The road was dust, gravel and rocks, when a truck went by he got showed in it all.
