Cheers Mawb, you're pretty much spot on.
Another aspect of paint correction is the ability to remove scratches in a paintless fashion. Now I have a pretty serious scratch to show you here. Alot of random scratches come out easily enough like I showed you in the opening post, as it wasn't just swirls I had totally removed. This needed more work.
The machine polisher with a compound will get rid of the majority of random scratches, but with this one being so bad it needed some extra attention. So I needed to wet sand it down..
Then polish it back to life with an abrasive compound, and further refine using a finishing polish..
The result? From all angles, no tricks..
This is, all in all, 100% paint correction. No need for costly resprays which can harm the potential resale value of your car
