so here are the pics about my huge damage on my fog cover..
but as I made the close pics I have realized a small crack on the glass
so the impact could have been really big one and/or the glass is too thin.
it is crazy because after looking at the pics I have double checked the glass with the cover off and I haven't seen anything
probably because of light conditions..
without cover this big stone impact would have def. broken my glass on little pieces.. BUT now I have a small almost invisible crack and my fog is still 100% usable
(I was thinking if the crack gets bigger but this glass is not like windscreen wich is flexing with chassis and the fog is fixed flexible so it should be fine
)
