I really it was the extremely hamfisted way I phrased it, but what I meant was you can't entirely prevent inflicting more swirls over time (you can minimise fresh swirling though) rather than never getting rid of those already inflicted.
I also disagree with the 99% of the time it being due to not working the compound. Whilst it is often the issue, the simple fact of the matter is if you're using something too abrasive for the paint you will never get a good finish regardless of how long or hard you work it. Similarly if the compound isn't abrasive enough, you can work it all you like it still won't remove all the marring... and then the longer you work it, the more it dries out, the more marring is inflicted.
So, I've tried:
By DA:
-CarPro Fixer on various 3m or waffle pads - awful, induced marring and wouldn't break down
-Optimum Polish - didn't really cut enough - put a nice gloss on the paint but didn't really remove or flatten the RDS' or deeper swirls
-3m PerfectIT Ultrafina III on Blue pad - again, nice gloss, not enough cut.
By Rotary:
-3m PerfectIT Ultrafina III on Blue pad - similar results to above.
Reason for using the all in one polishes with rapidly diminishing abrasives really down to lack of time....
I guess I need to dedicate a whole day or two doing the three step process with my rotary and see what happens then....! As in Fast Cut, Extra Fine Compound, Ultrafina.
Just expected on soft paint to achieve better results with less effort if I'm honest. My honda red paint on the last car would achieve 90% perfect finish with a AIO compound on rotary or DA. The Nissan paint behaves differently to any other car I've worked on.
On my Focus RS I achieved 99% correction and it stayed that way.
The Nissan, after achieving maybe 75% finish after the above, seems to swirl so easily it annoys me :S
