It's not paint.
The valve covers and the oil pan are made from laminated steel with a viscoelastic layer between, and sometimes coating. These products have been in use for a few decades. At my old brake friction material company, we used them as the noise-dampening shims on the back of the brake pads.
MSC, Material Science Corporation, made these. The head of their R&D used to work in the same department as I did.
Tap on the valve cover and the oil pan. They reduce the sound from the valvetrain and crankcase. In other motors, they're used to form the timing covers out of aluminum or stainless steel.

Not necessarily. That coating is probably oil resistant and temperature resistant, so it may be OK with a gash.
