scratch
 

i have 2 6inch scratches (yobbo key marks) deep right down to the metal. can these be touched up by a pro and will you notice them afterwards or is it a whole respray on the rear door that there on

that far down you won't get more than a 40% improvement with polishing :(

the rule of thumb is if you can catch them with your nail they will need to be repsrayed.

some pics would help.

oh right. so the cheapest way is to buy a touch up pen can a po touch it up and sand it in without the need of a respray.

it depends on the scratch really.

A chips away service will try to blow the scratch in and then blend.
