After a lengthy color matching process, I decided on duct tape silver for my upper grille block. I had to leave room to open the hood latch, though I make come back with a strip to reduce the size of the hole.
Total time spent: ~30 minutes
Total cost: ~$0, someone was kind enough to leave an auction sign somewhere
Also unclogged my washer fluid nozzles both above the hatch and on the hood.
EDIT: You can see where I went crazy with touchup paint. ^^
