At this point, either/or. Unless you know what color you want to go with, then I would do it in the body color now, saves work down the road if you're planning to pull the engine to do it..
Unless you can just clean it up temporarily with the engine in there, then just do the black for now.
I'm struggling with the same dilemma, I want to swap my engine out and paint the compartment while it's out. I just can't decide on a color. :banghead:
