So i'm nearing the paint phase with my car so need some advice on a few details. For a gravel rally car what should I be using for painting the underside/ interior of the car? Figure id ask you folks as to what holds up best particularly on the underside. Also is it better to paint the underside a particular colour for inspection purposes on competition cars? I've heard white because its easy to see cracks but is there actually any truth to this?

As far as the process of spraying the interior is it recommended to paint the cage, mask it off and paint the rest, vise versa, do it all in one go? FYI it will be all the same colour.
