Bit the bullet and just tried. Took me about 20 min total to remove both sides. 8 clips in total with 3 on the top and bottom and 1 clip on each end
1. Remove weather stripping and 4 torx screws holding the bumper in place
2. Pull the bumper cover out a little and you'll see the three top clips for each grill
3. Do the same to unclip the sides
4. This is where it got a little tricky...
- The passenger grill, I decided to just manhandle and pull. This worked fine and didn't damage anything
- The driver side, I actually just stuck my finger down and around to unclip. If you have long fingers it may be slightly easier. If you have one, I recommend using the tool that ForkLiter posted.
5. Finished! Now, I had to separate the silver surround from the slatted grill for PlastiDipping
