North West Valeting Needed for Deep Scratches

[FalconWood]

My Dad has some deep scratches on his bonnet that I have tried all sorts of polishes and Machine polish to get out - and failed!! The scratches are not down to bear metal but I have been told he needs a pro valeter with paint depth measuring skills etc etc etc to get the scratch out - sounds better than a respray!. Any suggestions of good Valeting companies/people in NW would be much appreciated - preferably in Preston area. Cheers

Thanks Gents
Its a start. Will let you know how he gets on. These are visible scratches but cannot feel them so we may be lucky. Thanks for the leads
