Body was dipped in grey primer about halfway up the doors as a rustproofing measure. The car exterior was primed and painted afterwards. No body color underneath except the overspray which happened when the body was primed and painted.

You do see a lot of cars with body color undercarriages, and while it is cool looking, it is not factory correct.

Trunk is all body color except up under the package tray and the bottom of the quarters. Those areas on my dart were bare metal (and covered in surface rust).
