If you want to know exactly what they look like without the screen color inaccuracy, buy a brand new GM pair. I just got two more with the umpteenth pair of hinges I just had rebuilt.

The original spring is not phosphate’d imo. The spring is natural spring steel which has a naturally dark looking finish.

A photo of my recently restored hood hinge and spring. The hinge was zinc phosphated and the spring was cleaned and oiled.

So is the consensus that the hinge is zinc, not manganese phosphate, and the spring is neither?

I plan on doing my hinges is a few weeks and have a NOS set of springs in the package that just need cleaned up.  Maybe just Evaporust and oil the springs?

Yes,evaoprust and some oil type protection on the springs. Hinges are the lighter phosphate as Lloyd pointed out. His are 100% correct and what the goal look should be.

If the springs are new GM why do you want to treat virgin spring steel with Evaporust? Were they rusted when removed from the package? I have had many hood hinges rebuilt which were supplied with new GM springs. Treat the new springs with the many bare metal protective coatings available if that is your preference. REM oil or any preservative in the machine tool industry works well. For those who drive their cars, I duplicate the hue of the raw hinges and springs after proper prep with epoxy and topcoat. Use Deep Creep for lubrication, same for door hinges.

No formula. I use what I have in stock and mixed a batch to ahieve the color.

Upon closer inspection it appears they have an old grease or oily coating inside the original packaging that over time transferred to the clear plastic side.  I'll just clean them up and oil as recommended.  Thanks
