Ordered the GMC Engine Olive factory paint from Jim Carter Trucks. A quart costs just bout $54 delivered.
Can is labeled NASON and its a DuPont enamel paint. Even in a sealed can the stuff stinks (vapors). I need to get some specific reducer from NASON (this stuff is heavy duty paint and I don't want to screw up my guns or the part).
I have not opened it due to the horrid oder (its the middle of winter and opening a window is not an option).
Once the temp gets above 50 I have a GMC valve cover from that I will clean, media blast, then paint and post pics.
