Have you, perhaps, ever met a Scratch Doctor?
Dear Primary Protector,
On Cybertron, metallurgists who work primarily with the surface layer of a Cybertronian's body are sometimes known as "skin specialists" or "scratch doctors", as they are most often seen when repairing superficial damage like scratches, cracks and dents. Certain versions of Swerve, Fixit, Alloy and Dermis have worked in this field, and—rather more disparagingly—some medics such as Knock Out are referred to as scratch doctors, to imply that they focus more on cosmetic maintenance than actual medical engineering.
Personally, I have never needed to visit a scratch doctor; my status as one of the Thirteen Primes grants my living metal a certain regenerative quality that most 'bots lack, and when I have need of more thorough repairs, I can rely on Safeguard or my siblings like Solus, Alchemist and Energoa to patch me up.
