Finishing is another factor you need to keep in mind when buying any compound. 

In this case, M101 tends to give you  an excellent high gloss finish. 

The users of M100 and M105 complain about finishes that dry out as well as cake up most of the time. This does not occur in the case of M101.

Also, M100 and M105 seem to leave a minor haze. And this is more noticeable in M105.

M101, on the other hand, is an incredible correction compound or polish that solves this problem. No haze has been noticed after its application. 


M101 has an extensively faster rate of the cut as well as a more intense leveling action than M100 and M105. The cutting action of M101 is also much more controlled. It has a heavier cut as well. 

Now, Both M100 and M105 are effective in getting the work done.  

However, the M101 will probably let you get the job done quicker and more effectively. It will also improve the possibilities of you going remarkably far with cutting.

Working Time:

Working Time

One significant factor for a cutting compound is how long its working time is. The longer it is the better. 

In this case, M101 has a much longer working time. On the other hand, the M100 and M105 both had shorter working times. 

Many users reviewed it as being their personal favorite for use with a lower-powered DA and MF cutting pad. 

Because it is extremely safe to use and allows them to work longer. Longer than M100 or M105.

Dust Splatters:

Dusting is another issue to consider when buying a cutting compound. 

Although the cutting action of both the M100 and the M105 is quite good. However, many users complained about the excessive flashing and splatter during the process. The cleanup afterward was a lot of hassle and took a lot of time.

The dust platter was somewhat lesser in M100 than it was in M105, nonetheless, it is definitely there. 

M101 on the other hand does not have this issue of dust splatter at all. Little to no splatter is noticed and even if there is any, it wipes off really easily.

Efficiency in Removing Defects:

M101 is an ultra heavy cut compound. As mentioned before, the cut is much heavier than M100 and M105.

Swirls, oxidation, sanding lines, scratches, and pretty much anything else that detracts from the surface of your paint can be removed using this. We are not talking about wet sanding but harsh ones here. 

Meguiar’s M101 Foam Cut Compound, is intended to be applied with a foam cutting pad. This is in contrast to a conventional heavy cut compound, 

Because of this, Meguiar’s M101 is relatively simple to use. And also it produces a finish more commonly associated with polishes than compounds.

The other two lag behind in this case. 

M101 also does it all without scouring the finish, whereas the other two M100 and M105 leaves hazes. 

Users reviewed that the swirls and scratches were melting away very easily. Whereas the other two took comparatively much more effort.

Which One to Choose? 

So, I believe you have already gone through all the factors of different meguiar’s compounds. Now it is time to choose one.

If you ask for my recommendation, I say go for the M101.

As you have already read, finishing is one factor that as a buyer you need to keep in mind. And M101 gives an excellent high gloss finish. Far better than both M100 and M105. 

The finishes do not dry out or cake up as well. 

Along with that, cutting should be another crucial aspect that will determine most of your job success. M101 provides a way faster rate of cut and a more controlled levelling action than M100 and M105. 

In terms of working time, M101 offers a working time that is much longer than the other two. 

And as for the effectiveness in removing defects, again M101 has been ranking higher among users. 

Another reason why most users love M101 is that there is no dust splattering while cutting. This is one thing they complained about most when it came to the other two. That they had to go through a lot of hassle to clean the excessive splattering from the M100 and M105.

So, after assessing all the pros and cons, my recommendation would be the M101.

Frequently Asked Questions (FAQs):

Harsh swirls or oxidation on extremely hard paint can be peeled off using wool pads. They are extremely abrasive pads designed for cutting or heavy compounding. It generates less heat, making the surface cooler, and eliminates heavy oxidation considerably better than foam pads.
