LOL i can understand that. You'll see the stuff on the glass. Typically you'll see the usual bugs, dust, road tar (that is annoying as hell and does not clean right off...use a degreaser for that). I've not yet come across a small pebble stuck there. I have had small road debris catch onto my clay when doing the lower body panel. By the time I felt the crunch...too late. Luckily it was on my vehicle and not a customer's.AncasterRFD wrote: ↑ I was worried about the clay picking something up, not noticing it, and digging it into the glass. I have a brand new windshield, so a little bit more OCD about it lol
If you're worried, something like rubbing alcohol works well or if you really want to go industrial...body solvent by Meguiar's.
