Not my car in question, but as u can see in the pic, the bird must've had an acid shit or something straight from Sellafield.
I've used the following products to remove the mark, but to no success:
Super Resin Polish
Obviously washed & snow foamed too.
Which means I now have an excuse to buy a nice orbital. However, will the orbital do what I want and remove that disgusting mark or will it be a respray job?
