If you look closely, I did not wrap the fenders, just painted them. We tried wrapping the fenders on the dirt car and we will NEVER do it again. Took several hours just to wrap one fender and was a real pain to peal off for painting this year. The vinyl job seen here was a little over $500 and included graphics for my helmet too. Paint for fenders was free in my case, so it really didn't cost as much as many people think. Keep in mind that a professional vinyl job will pay dividends with sponsors in the long run too. I realize that not everyone can afford to have some sort of wrap on their cars, but just giving you an idea of the actual costs.
Just my two cents.
