Hood Hinge Color

Short answer: Correct hood-hinge finish is gray phosphate — not black paint or zinc. A plater can do it (cheaper if you submit many parts at once), or OEM Paints (oempaints.com) sells spray cans that approximate the phosphate/oxide look.

For concours-correct under-hood and under-car finishes, see the High Performance Pontiac “Pontiac Tech” article by Jim Dietzler (consulting Jim Mattison). DIY plating is possible (a thermostat hot plate and Pyrex/stainless pans), but prep is everything — poorly prepped plated parts can start rusting almost immediately, even in storage.
