The bodyshop is getting closer to painting the undercarriage on the 70 Duster. I have not decided on how I would like the bottom of the car. For those that have done this in the past, which would you suggest?

Car is FJ5 and these are the two ways I am trying to decide.
Bottom full green treatment (with Lizard skin like material) with only the wheel well areas blacked out.
Or
Bottom of the car gray paint (with Lizard skin like material) so that it appears primer similar to factory appearance. Frame rails green body color and black wheel well area. Similar to the original factory detail.

The car is not going back stock and is not a number matching car so not worried about that.
