In this video GM shows us the paint process for the Corvette ZR1. Typically taking 6 to 7 hours per vehicle, the process starts with the body panels loaded onto a rig and passed through a series of spray and heating booths. Although the video skips the sanding and feather dusting process it's still interesting to watch.  Here's the recipe:

1. Panels loaded already covered in a conductive primer
2. gray primer is applied
3. bake for 30 minutes at 265 degrees
4. clean sand and feather dust dirt particles
5. spray base color coat to a thickness of 0.7 to 1.2mm
6. bake at ambient temperature (80 degrees)
7. spray clearcoat
8. bake for 20 to 25 minutes at 250 degrees
