Not a clue what it is, but I was driving in the early morning and the sun was directly in front of me and it looked like loads of tiny sand grain stone chips on the screen. I tuned off the heat(what there was with a cold engine) from the screen and used a semi rough cloth and my breath on a small bit to test and it came off. So the next morning I cleaned the whole inside of the screen and not a single one is there now.Only reason I new it was not the outside as my screen is ceramic coated so thought I would try the inside.
Evening all I've noticed something odd with my windscreen, when the sun is low, but bright, all over my windscreen it's like it's the upmarket metallic version. Completely covered in tiny sparkles, even when clean. Not a major issue but once seen, can't be forgotten! Any ideas?Cheers!
