Hey guys, I'm contemplating drilling a few holes on the underside of the front bumper on my new trk. Is there anything out of the ordinary when drilling a bumper that I should beware of. Will this cause the chrome plating to chip, creating a trouble spot in the future? Any input would be appreciated.

 

The previous owner of my truck drilled two holes in the chrome bumper for unknown reasons and they looked pretty clean- no chips or rust. If you do this I would treat for rust right after drilling.
