Without seeing pictures of the scratches or seeing them in person it's hard to say or recommend a course of action. I've detailed cars for almost 30 years. That being said, some scratches need left alone for fear of polishing off the clear coat which is very thin. Polish through it and you will end up with clear coat failure.
In essence, to remove a scratch, you have to polish the surrounding paint down to the level of the scratch. Sometimes that is feasible and sometimes not.
Again, need to see the scratch before giving recommendations. Be thoughtful in your choice of action.
