What's up with the gray primer on the underside of the car? ; )

I have found gray primer is typically found on the upper areas of the underbody such as tunnel & over axle. The lowe portion such as the floor pans are covered with black primer. Each plant and those applying the primers caused many variation in primer coverages.
