I have the same problem with my 2008 CR-V.  The dark gray surfaces
below the side windows seem to scuf easily.  I just try to avoid
contacts.  There is a posiblity that the scuff marks were present when
I took delivery of the car.

I spoke with the manager of the local Honda certified body shop and he had
recommended to me a product distributed by Honda called "Plastic Panel
Coating",  a 4oz. spray can.
He was even kind enough to give me a free demonstration with his supply.
Very friendly indeed!

The product worked very well covering up most of the scratches as described
in my original post. The sprayed-on coating will most likely wear away with
time but it does work very well and the spray can was only about 11 bucks!
How-ever be careful when applying it to the dashboard surfaces as the dash
has a different texture and if sprayed on too strongly (puddle) it may spot.
Use quick and very light brush/spray strokes, then quickly blot up the
excess.

Hope this helps!
