Black yes, but I'm still not convinced this isn't undercoating on this particular car or if this is a true representation of the Van Nuys convertibles that had the gray primer? Oh, well not to dwell on that.

I painted the bottom with my Devilbiss starting line HVLP gun (1.3 tip), I have a separate gun with a 1.5 & 1.8 tip that I've used with the epoxy primer and black chassis paint.

I'm using PPG DP50 epoxy primer (DP50 is the gray), they have other colors as well.
GM Restoration paint Black - for the frame and Front chassis components. This is what they used back in the day, now it's the same color/sheen but reformulated.


I've got all the suspension parts painted and ready to go when I'm finished with the rest of the bottom.
