What did you do to seal it? I don't want to put a front plate to mine, but leaving the plate holder is unsightly on my car IMO (no offense to anyone here), and can't think of a solution to cover the holes. I did check Bumperplugs.com, but they don't sell one in Ceramic Silver. I contacted them, and all they can do for now is make a custom set...for $149. Any ideas would be welcome!
