I'm stumped as to why you're having that issue tbh, the paint is hard but with how you're doing it and what you're using it should be coming up pretty nicely.
This session has cleaned most things up nicely maybe the scratches i'm chasing are just too deep. When i check with the lamp some areas are perfect. I have a few random deep scratches here and there.
I spent the most time on the drivers side rear wheel arch. Just above the curve of the arch a lot of scratches they would not budge. The drivers door has been painted so maybe this was damaged the same time.
I think polishing a car that had bad paint in the first place would give me more satisfaction. The two polishing sessions i've done with the das 6 over the past year and a half actually did a ok job.
Here is the roof i just did one pass with the sonax and black pad. There are 3 random scratches on the roof which i would have liked to get out but didn't even try as i've had enough. Maybe i need a really hard spot pad for the das 6.
Waxed her with collinite insulator wax.
