It all depends on what you are trying to achieve.
I assume since you are wrapping it, that you will want the fenders to look as good as the wrap, so you should get them professionally painted.
Personally, I do my own paint work, but my cars aren't show cars, and by the second night of dirt racing, they are chipped to hell anyway.
I use tractor paint in a cheap HVLP gun in my garage. Like I said, it ain't pretty, but looks good on the track and from the stands.
If you're running asphalt, you should have less damage on a weekly basis
