I would get a clay bar and give it a good going over. If the clay bar doesn't clear it up then it could be a problem with the lacquer.
Not that I’m aware of, however the colour of the 'normal' parts of the bonnet are identical to the rest of the car.Looks like a lacquer issue. Has the bonnet been resprayed at some point?
Yeah, in that case maybe a hand car wash would've caused it?WD40 used as shine does the cracking....just thinking out loud, not saying that has happened. Not so sure what caused the scratching in the clear coat.
