Any idea what these spray marks mean?

Picture of a prado I am looking at. Anyone know what the orange spray marks might indicate, if anything?

You've been marked for future catalytic converter theft.

Did someone scratch through the factory paint with jacks or stands, and wanted to rust-proof with whatever they had on hand?

Looks like someone marked jack or lift points. Seems like something that would be done to a fleet vehicle to make it simpler for any noob in the maintenance shop to put it up on a lift. Seems odd that one pair is on the axle and the other pair on the frame, though. I always lift either on both axles or only on the frame.
