I painted my factory 16's this weekend.
Lifted w/ OME 912's and Daystar spacers in rear, torsion bar crank and differential drop in front
Tires are Definity Dakota 285/75's (33" OD)
Paint color is Gun Metal Grey Metallic. It's a GM color according to the can. Bought it at Autozone, along with adhesion promoter, primer, truck bed coating gritty black and clear coat sealer.
The truck bed coater gives it a nice rough texture and hides all the imperfections associated with painting in your driveway on a windy day! Put that down over the primer, and the paint coats over that and it works perfectly!!!
I'll have to get a picture of them in the sun, as the metal flakes make them a little lighter in direct light.
