Now that u guts mdntion the back bumper i have a pin sized chip showing black underneath. Very very small no idea how it got there lol
 
I have a huge chips on my roof! Was unfortunate to be in the fast lane of a dual carrigeway while a lorry in the fast lane going the opposite direction must have gone too close to the edge and kicked up a load of gravel and dirt! Heard the thud and new it was gonna look nasty :(

Have it touched up now but it's still not level as the chip went down to the metal!
