I removed mine last weekend because it was blocking me from seeing cars that were tailgating me at night. It did not take long. used the claws of a hammer to pop 2 of the plastic clips on the inside to get at the wire connection. Its located on the lower right corner of the trunk lid when you stand looking at it. I had to use pliers to grip the ends of the studs so they did not turn out when I used the open end wrench to take off the four nuts (not sure I needed to do that but did it just the same because I did not want the studs to come out.)
I had already gone to Ace hardware and bought black plastic hole plugs - very thin on top - one 3/4 inch plug and four 3/8 inch plugs. Lowe's also had them but I liked the look of the Ace ones better. I then sanded them, painted them with touch-up paint, then clear coated them. I used P&G Parts to get my touch-up because the dealer did not have any and they and a 100% mark up. Bought both the small spray can and the small brush/tube. The spray can did not match but the tube paint did. It worked ok. I had to wet sand the 3/4 inch one twice before I was pleased with its finish.
When they were dry, I used a rubber mallet to pop the small ones in. Used a tiny amount of clear silicon on the 3/4 one to seal it (installed by hand).
Now I can see the tailgaters at night, plugs are not that noticeable, the car's looks are still good. I'm interested to see if it actually makes a small difference in gas mileage at highway speeds.
