I like the look. Not as eay to recongnize on a black one, but still a nice tough. I've considered that plus the mudguards on mine (red).
I have painted this type of material before. My wife's Ody is Silver and it looks terrible with the black mud guards. I had them painted to match and if you use a good flex agent and prep the plastic the paint will adhere pretty good. The only problem is that just like any plastic if it bends too much the pain will crack. Her's have held up great other than when she drug one across a curb and it must have bent it. The paint has some cracks now but otherwise no problems.
