Jeff, focus on the FRONT mount holes for the skid. Primer is heavy inbord, right up to the mount points. Then there's absolutely no paint outboard of the holes and the edges (paint-to-no paint) is fogged.
This shows me the skid risers blanked out the spray and the unpainted area shows direction of where the paint was coming from.
The paint was coming from the direction where the rear transmission seal is after installation.
