sorry Im not sure which categories this question belongs to so I just post it here.

After driving my RX8 for the first time in winter for ~ 4 months, I noticed i've accumulated quite a bit of rockchips on my windshield. Im not sure which ones I should pay someone $25 to repair. I'm not sure if im describing this right but all my rockchips are just on the outter surface and none actually shows cracking around the area where the rockchip is. Should i repair those anyway, or just repair the ones that actually shows a little bit of cracking? and its not something i can DYI is it, because i have alot of those little rockchips
