DIY or have a pro do it?

I have a little under a hundred small stone chips on my front bumper, the rest of the car looks very good. Should I try to touch up all the spots by using touch up paint and then sand and buff them or just have a pro do the whole bumper?

I believe it's on Brent Franker's site he has a complete writeup explaining exactly how he fixed the same problem you are talking about. I'm guessing time consuming but very doable at home with a little skill,work,and patience.
