**New** Meguiar's #105 Ultra Cut Compound Review!!!!
One of the hardest parts in detailing is removing swirls, and scratches in scratch sensitive or very hard paint. Some vehicles have paint as hard as glass! You can buff with a Dual Action polisher and barely change the surface. That is when one pulls out the rotary polisher. But sometimes even that is not enough! On a detail I completed last Spring, I was asked to detail a new Volvo XC-70 which had some of the hardest paint I have seen! I had to use a rotary and really work at removing the swirls. I spent hours buffing with very strong compounds trying to remove the marring. I succeeded in the end, but it was a real challenge!
Move forward 8 months, Meguiar’s introduces a new compound; Meguiar’s M105 Ultra Cut Compound. Meguiar’s M105 is on their aggressive scale, a “12” or the highest the scale goes in terms of aggressiveness. It is designed to remove 1200 grit or finer sanding marks by using “Super-Micro Abrasives”. This makes the product ideal for removing deep marring, scratches etc along with the sanding marks. The new Super- Micro Abrasives finish down to an incredible glossy finish. But keep in mind it is a compound so a polishing follow-up step in the Meguiar’s line-up will be needed. Meguiar’s M105 is white in color and has a familiar smell to it. If you have used some of Meguiar’s compounds of the past you will know the smell I mean; personally, I love it as it is mild and non obtrusive. That is a good thing when you are working with a product for hours per day! The M105 is a little thicker and not so runny like other products. It looks and pours very similar to Meguiar’s Solo Compound.

Since its introduction, most people are using it with a wool pad or specifically the new Double Sided W-5000 Wool Pad and are getting tremendous results! However, I wondered how it would react with other pads besides the wool. Of course I tried it with the Heavy and Light Cut Solo wool pads and well as the W-4000 Wool Pad, but I also wanted to see how well the product would finish down by changing the aggressiveness of the pads. **Keep in mind** Meguiar's M105 was designed to be used primarily with the W-5000 Wool Pad for best results. I am only testing it with a foam pad for comparison sake.
Winter has hit, with wind chills in excess of -27*C, so not many people currently desire having their cars/trucks/SUVs detailed at the moment. So I threw on a coat, plugged in a portable heater and went to work in my garage on my wife’s Toyota Corolla. The Corolla’s paint is quite “hard”, but it also happens to be a tricky paint to detail. Anyone that has tried detailing one knows what I am referring to. Too aggressive and the paint hazes easily. But not enough, and the swirls do not budge at all. I always need to step up to the rotary to do swirl removal, but it is a double edged sword as I need to be extremely careful on that particular paint.
After having used the new M105 with the wool pads and being amazed at how well it left the finish, I was curious to see how it would work on the Corolla’s tricky paint. I decided to use Meguiar’s Solo WDFP-7 Polishing Foam Pad with the rotary spinning around 1500 RPM.

The m105 finished down beautifully, leaving a clean and squeaky surface. I did discover one thing that needs to be mentioned, M105 is somewhat particular in the amount of product used. If you use too much, it become sticky and quite difficult to remove. However, after a brief learning curve, I discovered that less product was better and polished out easily. In fact, this is one of those times that less is more, so-to-speak. Also...no dusting of product! I found the product did not splatter as much and definitely dusted less than other compounds. The Corolla’s paint turned out awesome! There was very little haze and the tiny scratches on the hood from someone bumping the snow brush against it, came right out without a problem! Cool!
Now a lot of people have been asking on the Forum can you go to a LSP right after the M105. The answer is, I wouldn’t. Sure it finishes down incredibly well, but this is a compound which does require subsequent polishing step(s) to further refine the finish. In this case, I followed with Meguiar’s M02 Fine Cut Cleaner with the Dual Action Polisher. After topping with 2 coats of #21 Synthetic Sealant, the finish is flawless, not a mark to be seen!
Meguiar’s M105 is in my eyes and many others a revolutionary product that leaves an incredible finish! It is hard to believe that a polish so aggressive that one minute can remove 1200 grit sanding marks can finish down so well that a short follow up with a polish is all that is needed. All I can say is…Meguiar’s, why did you not have this last Spring! That Volvo left me frustrated and exhausted. With the M105, I am temped to phone the guy and ask for round two!
