I brought this up during the 1st winter with the MP3. Never did find any, but I gave up looking pretty quick.
Highly recommended for Canadian Winters. If you take a look at my front/rear skirts,INSIDE the wheel well, the paint is gone. the sand flicks back from the tires, and takes the paint off chip by chip. This is common though. Most cars with ground effects I've had I, have had the same problem. Dad's accord is really bad after 3 yrs.
