scratches i would say are a bit harder to argue a case.
I suppose it depends how much they value your custom. its really their word against yours.
Would the scratches polish out? what colour is the car? some colours show scraches worse than others. not sure what the TRIBOS paint protection is, but i doubt it will protect against scratches.
see what they say when you turn up.
incidentally just had alex noble on the phone saying the work will be authorised this afternoon some time. Maybe posting on here has moved things on?
