Oh my god. What a DIFFERENCE.

**kickslop** · 12-24-2007, 10:19 AM

I spent 35 hours so far on my new paint job (nightmare). All with 1500 grit (yes, it was necessary) and a 6" rotary (not DA) with 3M Perfect-It III compound on a synthetic wool pad (it`s all I had).

I got my DA rotary (Ultimate Detailing Machine) today after dealing with 2 extra days of shipping thanks to USPS and Xmas season.

WHAT AN AMAZING DIFFERENCE in:

a) Effort required

b) EFFECTIVENESS -- greatly reduced time, and I`m technically not even using the right foam pad as that shipment STILL has not arrived, even though I ordered it and it shipped the same day as the UDM unit

Generic "heavy duty rotary polsiher" people, you don`t know what you`re missing. It`s like doing long division with 8 digit numbers by hand vs. with a calculator.

Now back to work on my car.

Just a happy newbie and convert,

I`m not being argumentative, I`m just not sure what is the point of your thread....

Are you saying the UDM is more effective than a rotary at removing 1500 sanding marks?

Please explain.

This thread has left me confused...

**SpoiledMan** · 12-24-2007, 12:30 PM

Do you know the *difference* between a rotary and DA?

**kickslop** · 12-24-2007, 12:35 PM

Sorry guys, don`t read too much into this.

I`m new to this and was just sharing excitement about something making my life ~4x easier. than it has been in the last 2 weeks of arm-breaking work.

Yes, I know the difference between a rotary and a DA.

I am not in any way trying to start a religious debate. I`m not in any place to.

I didn`t mean to "startle" any veterans

The UDM is a DA but you mention rotary as the same time. Which are you using?

**kickslop** · 12-24-2007, 02:20 PM

I`m using UDM, a DA machine.

I consider DA a type of rotary. It does afterall rotate. But for the sake of being more accurate with standard naming, I`ll just call it DA from now on.

I can see why everyone is confused

just call it a UDM!

so you are comparing a UDM to hand polishing?

**KnuckleBuckett** · 12-24-2007, 03:09 PM

Yikes this thread is a bit of a mess.

Let me see if I can help...

UDM, PC are random orbital buffers. Neither spin, they vibrate in erattic orbits, thus are not in any way a rotary.

Flex is a true dual action longer throw random orbital buffer. It does not spin though it rotates thus will not burn your paint. The Flex utilized two seperate (dual) orbits, thus is not in any way a "true" rotary.

A rotary spins in circles (like a tire), thus the name.

The orbital buffer types are great because they are safe, effective, and easier to learn how to use effectively. It is difficult to impossible (not a challenge folks) to damage your paint with this style buffer.

That said.

A rotary in skilled hands is faster, more effective, and able to provide a far better end finish than the random orbital machines. However a rotary can easily cause paint damage in the hands of the unskilled. Learning to use a rotary is best practiced on scrap doors, hoods, etc., before attempting on a personal or customer vehicle.

I expect that most professional shops have both types and that the average Joe is best served by sticking to a random orbital.

I use a PC but am considering purchasing a Flex this coming summer 2008.

Here`s what I am dealing with. Please note, the "after" side is only after wet sanding and compounding. No polish, no wax, no glaze, etc. It`s probably FAR from exellence, but it`s good enough for me (once it`s finished fully).

I repeat. NIGHTMARE paint job. Long story I am not getting into.

Actually, the UDM does rotate at a pretty good clip even when you put pressure on it and is notably more effective than a PC. A rotary is definitely more powerful (I`ve been using a PC 7428 rotary the past few weeks) but the UDM is very useful on vehicles that only need a light polishing.

I`m sure it was my machine or technique, but the UDM has been VASTLY more effective for me at heavy compounding work. But, I`m not looking back... I don`t even care to learn how to use the rotary properly at this point. I`m just a guy with a car -- not a shop or pro detailer.

And yes, the UDM rotates
