Another thing I did last week, was remove the North American bumper guards. Yes, there are those purists that will say that on our NA-spec cars, they belong there, but mine had worn out the liners/gaskets, and I felt that they needed to go. I had always planned on taking them off, but years of apathy put it on the back burner. Lately, we've been driving it down to our summer cabin in Point Roberts (a unique bit of the USA accessible only from Canada), and I end up staring at the ugly bumper guards all day when we're hanging out on the patio.
I always had it in mind that I would simply plug the holes with chrome carriage bolts. I haven't found any locally yet, but I saw some 5/16" stainless ones at Home Depot, so I picked them up. I used my dremel with 2 levels of polishing; first was the wire brush, then the polishing attachment. I also used some chrome polish, and now they are very shiny. I used rubber washers on the back to shape/form to the curvature of the bumper and help keep the nut tight. Unless you come up close, you can't really tell. When I come across a place that has some chrome carriage bolts, I'll eventually swap them out... probably another 15 years from now.
