1. Take stock grill out. Two pop tabs on driver side and few across the top and on the passenger side. There are two square socketed plastic screws on the inside of the grill that can only be accessed from the backside of the bumper.
2. Dremel out center slates carefully (see pic below for idea)
3. Sand smooth
4. Use spot filler Bondo if necessary, a little goes a long way and resand smooth
5. Use plastic primer or good etching primer
6. Check for imperfections and fix if necessary
7. Get Duplicolor spray paint that matches your color code. Mine was Ultrasilver.
8. Mask off the areas you don't want painted
9. Spray several good coats of paint without runs! (4-5 coats)
10. Spray a lot of coats of Duplicolor clear without running (5-10)
11. Custom cut APC mesh to fit top opening and bottom ensuring clearance around the
places that hold it to the bumper. You can attach it using epoxy carefully, which is
probably a better idea than the way I attached my mesh.
12. Paint mesh if desired, (BBQ black here)
12. Carefully reinstall grill and enjoy!

This is the cut, masked, first coat painted, and ready for clear picture. It's the only one I have during the process.
