I was driving in the slower lanes well behind a semi (about 100ft) and all of a sudden, I see a brownish-white colored rock the size of a nickel in diameter impact my windshield right in front of my face. It was loud as hell and scared the crap out of me. There is now two small rock chips one on top of the other on the glass right above the speedometer. From the sound of the impact and the size of the rock, i was surprised it didn't crack the windshield. Anyway, does anyone know how to buff out or smooth out the chip so it's not that noticeable? It is right in my L.o.S. and is a bit annoying.
