accumulator: sorry for the confusion, i was just mixing thoughts in my mind. i had your post here:
Wet Sanding
i was just recalling the info about how removing marring/scratching using the Ultra might not necessarily be its intended use as you more eloquently stated. I always try to think of hand applications as a lesser playing field when it comes to results.
when i am going for swirl-removal, i tend to think Paint Polish first ... maybe even two passes
my brain just thinks of ultra as a reviving compound to get deep down.
My personal results on my 12 year old BMW told me that the Ultra did more for reviving the paint's color than getting rid of its flaws. I've never dealt with the fabled rock hard audi clear and can't compare w/ your experiences and what the UP does for it.
Your most likely right in saying that the PP seems better to my eye because of the smooth finish it leaves.
I don't doubt the Ultra's strong abrasiveness, i just noticed that the PP seemed more at home as a swirl removal tool ... and the Ultra as a first step product for restoring a car w/ some damaged paint. I do agree it is more abrasive, but found it catered more to neglected, oxidized finishes, rather than just scratched ones
sry for the confusion ~~
