Simulate the pebble grain? I just primed and painted over the original burlwood.

I think what you are seeing is how the paint with the metallic flake is showing up in the photo. It will eventually be the body color.

I just bought the Camaro pod, cut a hole in the top plate of the console, flanged it, pop riveted the pod to the console plate, spread aobut 5 layers of filler (I suck at filler), primed and painted. I also had to clearance the top of the console for the gauges to fit.

What also doesn't show up is that I glued 1/8 foam to the side of the console and stretched the same fabric that I used for my seat covers over it.

Took longer than I figured it should, but I am happy with the results.
