Use Ultrafina with the blue Ultrafina pad. Trust me on this.
Yeah, Scott, that blue ultrafina pad is a great pad... far better than any foam pad I've used, but I don't have a backing plate big enough to use it comfortably, and the eight inch size is huge. I'm gonna try and order some of the six inchers from England.
OK, so more results...
I kinda changed my plans a bit. I did half the hood with Ultrafina and a brand new white finishing wool pad. There were alot of compounding marks and holograms. Key word there is "were".

UF and the finishing wool destroyed them fast while leaving a mirror finish. I got alot less sling with the wool than I was getting with UF and foam. It still required using a sling bucket, though. The finish it left is beautiful.
I then finished the other half of the hood with PO85RD and the other side of the finishing wool pad. This took *much* more time than the UF. UF is a simple four-pass-and-your-done deal. With PO85RD you need to pack a lunch. It did do a good job of getting rid of the holograms and compounding marks, much to my surprise. It also left a finish almost identical to the UF; it does look a bit glossier, but not enough to be concerned about. It took quite a bit more than twice the amount of time to do this half of the hood than the UF side.
I then moved on to the roof with PO85RD and a black LC foam pad. This combo just didn't have the chops to get rid of the holos and compounding marks. I thought for sure that it would at least gloss up better than the finishing wool, but it didn't.
Moving onto the other half of the roof, I used UF and black LC foam. It did a much better job of taking out the compounding marks and holos. However, it did not finish as well as the finishing wool did. This was a big surprise. I thought that the foam would finish better than the wool, but not get out the marks as well. The sling is harder to control with the LC foam pad than the 3M Ultrafina pad.
On this particular car, the white finishing wool/UF combo flat out wins, no contest. Yeah, you could get a slightly better shine with the 85RD, but the additional time required just isn't worth it.
If I had the money, I would buy every Autopian an Edge 2k White Finishing wool pad. It's that good, and it's a deadly combination when used with a good finishing polish like UF, PO106FF, or PO85RD. You can buff with your eyes closed when using UF and white wool. It's that easy. And F A S T. The only other pad that really compares to it when used with UF is the blue pad that Scott mentioned. If we could just get it in six inch size here in the U.S...
I had been having mixed results with UF and the white wool, but I'm sure it's because my pads were on their last legs. It also feels like Edge has changed the quality of wool being used in the finishing pads. The ones I broke in today felt much softer and fluffier than my last pads.
A few weeks ago, I conceded that you can get a better finish with finishing foam and PO85RD than you could with finishing wool. That might be the case for some finishes, but today the wool triumphed over the foam by a long shot. UF and wool destroyed compounding swirls and holos in four quick passes, while leaving behind a beautiful gloss.
M105 followed by UF on either the 3m blue pad or white finishing wool makes a formidable combination when you need serious correction. I'll go snap some pics of the hood, but you're not going to be able to see a difference between the UF side and the 85RD side.
