Nylon stocking/pantyhose/legging material stretched around a prepainted part. Can even be don with spray bombs! Lightly mist your texture color through the nylon to get your pattern.

Adding some smoke/clear black will further add depth and help with the scale illusion of the parts. I've also seen people use cheese cloth, drywall tape, and mesh sandpapers for similar effects

I forget which channel I watch that sometimes does this.
