A lot of mopar guys lose their minds when they see blacked out trunks and engine bays. Yeah I guess I am among them.
I can't speak for the US, but back home in Australia when any of us saw cars with blacked out engine bays or trunks we instantly wondered what the owner was hiding. A quick black spray job and years of rust just melt away!
I have even seen flippers that blacked out over ALL wiring in the engine bay!! This is most likely to be on a car that once you buy it, the first thing you have trouble with will be electrics!
