[garychen0919]

Hi, I am thinking to buy Ultimate Compound or M105; however, I don't know which one is much stronger,and how much different?

thanks

Re: Ultimate Compound vs M105

M105 is much stronger.
Ultimate Compound I think is comparable to M83 in aggressiveness

Re: Ultimate Compound vs M105

According to the Aggressiveness Order I would think SwirlX is closer to 83 than Ulitimate Compound. From personal experience I would say that UC is closer to M105 than it is to M83 or maybe right between 105 and 83. (This is my own opinion and not Meguiar's).

Re: Ultimate Compound vs M105

Ultimate Compound is a little stronger than M83, which is about 6 out of 12 on the cutting scale. M105 is a 12 out of 12 on the cutting scale. I asked the same question a few days and got plenty of replies. Check the Ultimate Compound review thread started by Michael Stoops.

Time to start a new, dedicated thread just for the answer to this question



Posted yesterday to page 2 of this thread,

Ultimate Compound - Who's used it, what do you think?


Question

Can anyone discuss the cut of Ultimate Compound to the new DA-approved M105? I'm not looking for chemical design, just a simple answer. Which one has more cut?

Answer

M105 is more aggressive than Ultimate Compound.

M105 is in our Professional Line and primarily formulated and targeted at people using rotary buffers to remove sanding marks out of fresh paint in body shops. (Generally speaking, people in this industry have a high skill level for working with paint care products as they do this for a living).

Ultimate Compound is in our Consumer Line and primarily formulated and targeted at people using a DA Polisher or working by hand to restore a neglected finish on factory paint. (Generally speaking, in the Consumer market, the average person washes and waxes their car 2-4 times a year. Online enthusiasts that hang out on discussion forums and work on their car more often don't fall directly into this category as they know more and tend to have a higher skill level for working with paint care products).

And just to note, this subject has been brought up and discussed in one of these two threads,

Ultimate Compound
M105 Ultra-Cut Compound - New Formula DA Polisher Approved

Maybe someone can read through the two threads and their multiple pages and verify?

When you get to this level of aggressiveness, unless you're working with a rotary buffer both products are going to get the job done equally well.

When working with a DA Polisher and ESPECIALLY by hand, your TECHNIQUE is more important than whether you're using M105 or UC

So the questions are,

• What are you working on?
• What is the goal?
• How are you applying the products?

Well, I would consider that immaterial......if the technique you are using doesn't change from product to product.

I'm relatively new to all this, but I have tried a number of these products.

Currently using Ultimate Compound with a rotary, and I must say it takes a LONG time to get out moderate to light scratches/swirl marks.

Tried SwirlX first, and same deal.

Don't get me wrong.....the tiny tiny swirl marks ARE removed....but the ones that take a LONG time aren't that deep in my view....

I think all these are made to be 'safe' so the average user doesn't mess up his paint job.

And another observation.....all these products do the same thing....but they all have such catchy names.......I think this is all a marketing ploy.

Gonna try the 105 when I can figure out where I can buy it.....

ALL these products should have a bar chart like the 105 does, that would let a person know what the agressiveness is...........I'm thinking these products are used by a lot of people that really are willing to spend quite a bit of money for quality..........so I suggest some type of indication as to what the products do from a comparison standpoint.....otherwise, it's just hype what you read on the label.............z

Re: Ultimate Compound vs M105

PS. Just noticed that the last 2 also have a bar chart, so it's the middle 3 that need an agressiveness indicator.........z

Re: Ultimate Compound vs M105

Zardiw, did I get it right? You said that you used Ultimate Compound with rotary buffer? It's not formulated for that. UC should be strictly used with dual action polishers and hand applications. No wonder it took extremely long time to correct those defects.
If you primarily work with rotary buffer M105 is the right compound. You can easily remove serious defects including 1200 grit sanding marks. However M105 dries pretty quickly and therefore it has pretty short buffing times. But its cutting ability is powerful.
If you plan to work with DA polisher you could use both compounds (just make sure you get DA approved version of M105). As Mike said, working with random orbit machine and having good technique would enable you to get almost identical results with both products: M105 and UC. UC would extend your buffing times.

The reason being the products are from different lines and use different technologies and application methods. They were never intended to be compared, but the chart was created to provide a rough idea of cut levels.

Re: Ultimate Compound vs M105

Yes. I can't get 105 at my local industrial supply store. And I'm assuming that UC breaks down too fast in a rotary.....tried it by hand and it seems to work good........Bought some 3M Ultra Compound.......that should do the trick........Tired of screwing around......z

Re: Ultimate Compound vs M105

M105 dries pretty quickly and therefore it has pretty short buffing times.

Well, to prevent fast drying, you can just mist with water, right?

That would be Kevin Brown method: pad priming and water mist to extend polishing times. Here's the link:

Re: Ultimate Compound vs M105

I'm using UC on a PC setting 5 for 4 passes with moderate pressure and am still leaving maybe 10-15% of swirls using a yellow LC pad. Should i switch to the M105? or apply more pressure or work slower? I just don't want to spend a lot of time on this vehicle. I'm still learning how to Troubleshoot various paints and methods to use.

Sheesh, how many places did you post this same question??? Seems to be the day for this today! Don't get us wrong, we're not busting your chops on this, but you don't really need to ask the same question in multiple posts - it's best to keep the discussion going in one location so as not to confuse people.

But as we said in another post, if your technique is good and it's taking that many passes to remove defects, it may well be time to step up to something more aggressive. In this case, that's probably M105 or even the DA Microfiber Correction System.

Re: Ultimate Compound vs M105

i apologize. i was kinda in desperate need of a quick answer and didn't realize i posted it so much. Thanks though for the great responses. Picked up some M105 on the way home from work in case more pressure doesn't do the trick.
