M100 v. M101

[The Guz]

Is there big difference between m100 and m101 in terms of cutting? My main compound is Nanolex Heavy Cut which is superiour compared s3 xxl. However m101 with mf pad cuts little more and faster especially if you use water to to do couple more passes. But m101 smells bad and is thick studf and i have read that m100 is much more nicer to use, but does it lack behind m101 in cutting power? If so, then ill contiune to use m101 as my heavy weapon. And i use Rupes machines and mostlt mf pads for compounding.

M101 has slightly more cut than M100.

Another Compound Question (M100 vs M101)

Most users find that M101 Foam Cut Compound cuts slightly more than M105 Ultra Cut Compound & M100 Pro Speed Compound, even though they are all rated at 12 on Meguiar`s cut scale. You are correct, M100 Pro Speed Compound is more aggressive than D300 DA Microfiber Correction Compound, but was not developed specifically for the Microfiber Cutting Disc like the D300 was, so you can experience more dust, but for the most part, the feedback is great on M100 Pro Speed Compound applied with our DA Microfiber Cutting Disc, when more cut than D300 is needed.

In my opinion I would try to stay with our complete DA Microfiber Correction System of liquids & pads for your "work horses", which include the DMX5/DMX6 DA Microfiber Xtra Cut Discs, DMC5/DMC6 DA Microfiber Cutting Discs, DMF5/DMF6 DA Microfiber Finishing Discs, D300 DA Microfiber Correction Compound, D302 DA Microfiber Polish, and D301 DA Microfiber Finishing Wax. Especially when you are completing cars in under one hour including wash, in our opinion the design of this system will give you maximum efficiency. There are situations where technicians are applying our DA Microfiber Correction Compound to the entire vehicle without wiping off the residue, and going right over the compound residue with our D301 DA Microfiber Finishing Wax, with good results. Of course for best results, proper priming of the DA Microfiber Cutting Discs are vital as well as frequent cleaning of the DA Microfiber Cutting Discs (with ideally compressed air or a microfiber towel, some use water in a bucket to clean the discs,) but again the above technique is OK by Meguiar`s if the situation calls for it, like a very short amount of allotted time.

Again we think our DA Microfiber Correction System will deliver great results & efficiency for your situation, also with the fact that it is easy to train technicians how to use, but as you have found M100 Pro Speed Compound is a great for times when more cut is needed, like very hard paint or isolated deeper scratches.

If you haven`t already, we would also consider looking into our S6F3000 Professional Unigrit 3000 Foam Finishing Disc, paired with our S6FI Unigrit 6 Inch Foam Interface Pad. You can buzz through Random Isolated Deep Scratches or an area on the vehicle with a lot of heavy defects with a couple spritzes of water and a couple passes, and our D300 DA Microfiber Correction Compound along with DA Microfiber Cutting Disc typically pulls the sanding marks out easily. More information on this set up here, The Power of 3000 Grit.

Hope this helps. Feel free to ask further questions.

I wouldnt say slightly. With Rupes duetto and mf paf the M101 beated the ```` out of M100. I ordered more M101 and going to sell M100.

I`ve actually had the opposite experience on my hood after a repaint. M100 on a Meguiar`s burgundy foam pad out cut M101 on another Meguiar`s burgundy foam pad using my Rupes LHR15 MKII.

That is interesting. I have read few instances where M100 outcut M101. However atleast on my BMW test hood and 2011 Audi A4 i did recently, M101 was much much better.

Just got done playing with new Flex 3401, 5.5" LC Force Hybrid Gray Heavy Cutting Pad, M101 on a 2006 Ford E-250 Fleet Service Van, 151K miles. 4 3/8 Flex Backing Plate.

Before (after clay):


After 4 passes, medium arm speed, light to medium pressure, speed 5 on Flex:




Obviously not perfection but a fleet vehicle that has likely been run through a tunnel was twice a year for the past 10+ years, rode hard and put away wet. Didn`t bother to refine w/ a follow up polish/2nd step as, well...at the end of the day while you can actually `polish a turd` it`s still a turd, just a lot shinier. Between the deep scratches from Techs throwing tool bags on the hood and all manner of abuses (what appears to possibly be solvent pop among others), for the time involved and the results. definitely a nice combo for quick fleet work. For comparisons sake, did the hood of a similarly abused van using GG6, D300 w/ microfiber cutting disc and it took over twice as long, 6-8 passes slowwwwww passes. Obviously Flex vs. GG is no real comparison but it`s all I had to contrast with at the time.



I`m thinking I like the M101/Force Hybrid/Flex combo. Since this was not really a `vehicle of consequence` I started out heavy, next time maybe I`ll go with Orange pad and M101 and see how it plays. Have about 20 other Fleet Vehicles to play with, in a variety of conditions. Think next I`ll find an equally beat van and try Rupes LHR15 Mk II w/ Rupes Blue Course pad on one part, the Rupes LHR15 Mk II w/ Griots Fast Correcting Creme on Griots Garage BOSS Fast Correcting Foam Pad on the second and the `ol FLEX/ForceHybrid Gray/M101 on the third.

I had used M101 w/ the GG6 and LC Flat yellow cutting pad in past but it was less effective than the D300/Cutting disk combo but the Flex/M101 pairing beats that in about half the time/effort. FWIW, I did try M105 for the first time during this project, after one section that turned into glue, threw it in the trash. Read all the buffdaddy and other recommendations on how to use but don`t think it`s worth all the trouble when other options are just `load up and go`. I primed the pad then when with about 3 pea sized drops per section and some of my sections `grew` a bit but didn`t really seem to phase the M101. Did notice that overuse of the M101 did cake the pad which was cleaned on the fly using the orange LC pad brush. I used the same 3 pads for the entire thing, broken down over 4 days:

Day 1: Hood and Front Fenders/front Doors
Day 2: left hand side of truck
Day 3: right hand side of truck
Day 4: back of truck

As i was running out of days and was doing this after a 6am to 3pm workday each day, I hadda break it up in this manner. Didn`t get to roof of truck as Van needed to be pout back into service today. Besides, everybody who works here is less than 6ft tall so no one will ever see it!

After each day used, PB Tornado Pad cleaner sprayed liberally on pad, took `em home and washed in washing machine, Heavy Cycle, Hot Water, 3D/HD Towel Kleen. While the backside/velcro still looks like new, the face of the pads are looking a little `used` and just a bit `furry`, but really not that bad. Thinking that may be more due to `aggressive` use of pad brush when cleaning on fly trying to dig out caked up M101 when I over used it. I was also jamming those pads in all manner of places, over black rubber vinyl pieces as I enjoyed the Flex forced rotation.

Back on topic, Now that I have FLEX, will always have M101 around. Very little dusting, easy removal and very effective. Will have to try on Rupes too.

Nice work and interested to see how it goes. Could you test Zephir vs GG Fast Correcting Cream vs M101 with the same pad so that the results are most compareable. Thanks.

Got any suggestions as to pad and machine you want me to try with? May be a while, winter has returned to Cleveland and once outside temps drop below 30 for extended time, not economical to heat warehouse to 55-60 degrees just so I can play (so I`m guessing the guy who pays the bills around here would say; some people just don`t understand the importance to this kinda stuff...expense be damned!)

Can use:
GG6
Flex 3401
Rupes LHR15 Mk II
Rupes Mini

The FCC creme/BOSS pad came about as someone asked for Flex/Gray Force Hybrid/M101 vs Rupes LHR15, GG Fast Correcting Foam pad w/ FCC.

I have a set of Rupes machines so please use Rupes 15 MK II. Do you have microfiber pads? Those i use mostly for correcting, but i guess Boss FC foam would be good test equipment.

Got some Megs Microfiber cutting discs, Rupes Microfiber cutting and a few LC microfiber cutting. Have yet to use the Rupes or LC microfibres.

[Joel79]

Did you do any testing?

Not yet...may be awhile...Cleveland and all. Need a few days that aren`t freezing to warm up warehouse efficiently after I get done with current vehicle which doesn`t need compounding. Figures.

BudgetPlan1- IMO the GG6 would provide the most info for the most people and it`d be easiest to extrapolate from that machine to what one might expect from the others (i.e., Rupes). I wouldn`t use the Flex3401 as its forced rotation makes it a wildcard type of unit.
