Ive made a second attempt at removing the scratches and swirls from my black paint work on my Audi A4 and still nothing happened

I used a Kestral DA polisher with 3M compounds and all the correct pads etc etc. What am I doing wrong here?





Ive heard that Audi paint is harder, is harder the correct word? Well I think you'll know what I mean?
Any how am I supposed to keep going over the paint work til the scratches/swirls have gone?
Am I supposed to push down a little harder?
Ive followed the instructions, watched demo's on youtube etc and copied them but still I have f**king scratches and swirls

How much does it cost to get a car professionally done? As in done I mean paint correction.
