Pontiac Firebird 1967-2002 - Under Hood/Body color

My car is Pewter and under the hood and body seem to be something similar but flat.. Anyone know this color. Next weekend I am going to hit a few rust spots and would like to cover them with the OEM paint.

It's OEM base coat without the clearcoat.

SO what would you do ? go to a gm dealership with the paint code and they would have the paint? I know it,s kind of a dumb question, but the paint in a can from napa isn,t close

get the paint code from the door jam, and have some mixed up, maybe a quart or so? not real sure how much you'd need and have it painted. let me see if I can find the link in appearance section that talks about this very subject.

lots of pretty good info. in there

If the top looks like that, have you looked underneath the car? Might be a good time to knock it all out if you spot any issues under the car also.
