i have never replaced the stripping on my car but what ive seen it should be that diffucult for a noveice like my self to it if i wanted to save some$$$.
your gp like mine has a 3yr / 36k bumper to bumper excl bulbs and tires, if your under warranty and it shows no sign of owner abuse or neglect i cnat see why your local and friendly pmd dealer wont replace it..
but not ot hard cause the whistling air must get annnoying...
