Ok, finally got a chance to take the UDM for a spin and compare it to the 7424. I taped off my hood in half and used the UDM on one side and the 7424 on the other. I used Menzerna's Final Polish with a white LC CCS pad on speed 6 for both units. I also worked both sides equally as long (3 minutes) and compared the results to see if there was any difference. The UDM side took more swirls out and also broke the polish down better than the 7424 side, which means the extra power from the UDM is going to good use. While I only had very minor swirling on my hood, the extra correcting ability will really come in handy when dealing with a heavily damaged surface. Don't get me wrong, the 7424 side still looked good, but the polish definitely needed to be worked in and broken down a little more to get the same results as the UDM side.
While both machines are basically identical in the way they work, the UDM is a MUCH improved machine vs. the 7424. Just as I thought, the extra power of the motor makes this unit much harder to bog down, which will come in handy on heavily oxidized & swirled finishes. The extra power seems to also translate to being able to break polishes down a little faster, saving time and also the possibility of doing multiple passes on the same body panel. The vibration factor has also been severely reduced, as the UDM operates much smoother than the 7424. Working all day with the 7424 can be very tiresome because of the vibration. (this improvement alone would cause me to buy a UDM and ditch the 7424)Weight wise they feel the same in the hand, so this is a draw. The body of the UDM felt a little better in my hands. The shorter cord wasn't that big of a deal to me, as I was still able to throw the cord over my shoulder with plenty of slack. All in all, anyone looking for a polisher capable of tackling pretty much any situation/paint condition should seriously consider picking up a UDM. It has taken the concept that has made the PC 7424 a staple for over 10 years in the detailing industry and improved it in almost every way. I'm thrilled with the new machine, and cannot wait to tackle some more vehicles in need of "saving".
If I did not currently have a polisher and was in the market, I'd definitely wait for the release of the UDM. IMO its a much improved machine.
If I did already have a PC, it would really depend how often/heavily you are using the machine. If its only for occasional use then you might be better spending it on product. But anyone using the PC regularly should definitely consider the upgrade. Its worth it IMO.
If anyone has any questions just let me know, I'll answer them the best I can.
