re-paint

So while looking and paying close attention to my front bumper, it has a TON of rock chips, it is evenly pelted by sand and rocks (apparently Az has alot of those) it is entirely covered in tiny white spots and my hood had larger more obvious ones, should i re-spray my hood and bumper? if i do...

HI, just wondering if anybody out there has painted their 05-09 mustang Grabber Blue. I would love to see some pics if you have done it, because I have this crazy idea in the back of my mind to do it to my 06 :)
