I had this on the bonnet (hood for you US folk) of my BMW E82. When I saw it I was totally confused as to how it had happened.. it looked like someone had emptied a skip full of rubble on top of it.
The day I sold it, the guy who took it in told me it was down to a poor re-spray. He didn't specifically say what was wrong, but it very quickly became clear that half the car had been 'repaired' at some point prior to my ownership, with no documentaiton to prove it.
Made sense why two of the alloys were mismatched paint shades...
