has anyone compared these two yet?iv seen a few threads on each where on lighter color cars with a foam pad they are LSP ready with out stepping down to a finer polish. I am looking to possibly add 1 of these to my arsenal for 1 steps with a medium cut foam pad. I currently use a flex 3401 vrg.

I thought M105 was the shizzy until I got some M101. It has SO much cut, barely dusts on a MF pad, and the finish is unbelievable on most colored cars. Honestly, I just 1 stepped my mother in laws mini van with Megs MF pads primed with D300 and then added 4 dots of M101 and D300 via my Rupes BigFoot starting on speed 5, then making 2 passes with 6 and move back down for final pass with 5. I literally went straught to Opi Coat after this process and it was LSP ready. Bare in mind it is a very light metallic pewter color.

Yeah.... I don't want to hype M101, but I was able to quickly remove, by hand, and a 3" cyan pad, some sanding light marks left by somebody on a Legacy GT, using it.

I tried 101 and 100 today for the first time. I even tried 100 with a wool pad. I love them both. I can see replacing 105 with 100 for most jobs. It did a lovely job with a yellow B & S pad.

I haven't tried m101 yet, but I have tried m100 and it's pretty good. Unless one of my friends has a bottle of m101, I probably won't get to try it out as I have other stuff to use and I don't use compounds as much. And if anyone has m101 out there, I am not asking for it. I want to finish what I have already bought. (fg400 and s3gold)

Sorry for not answering the question. I haven't used fg400 as a one step. The times that I have used it, I've used a finishing polish afterwards. The colors on those cars were either dark or bright silver. Probably on white you can get away with one stepping fg400.

I have only one stepped with sonax perfect finish on a medium polishing pad on my car which has soft paint and is white although I have seen pictures of other guys using spf doing a one step on black ferraris with rupes yellow pads.

I think you do need either fg400 or m101 unless you are using and like some other compound. I'm sure both are great. I have not heard a bad thing about either product. I would choose based on either brand preference or if you are more comfortable with smat or dat. I am more comfortable with dat products so I would go with fg400.

This is my current dynamic duo and probably will stick with it for awhile. If a finer polish is needed, HD polish is great as well as sf4500. I would like to try scholls concepts s40 as a finishing polish and s30+ as a one step whenever I run out of spf, but probably won't be for a long time.

vegas911gts you may find that SC S30+ is not that much more cut then S40. Do not think you will much correction out of it in my experience. The new S20 (blue) may be something to look into if you are looking for balance between cut and finishing but then this has S17+ written all over it.

Back to the topic, I have very little time with both compounds, test panels, I find that FG has less cut but is good enough for most jobs where as M101 will just power through most defects. On softer paints I would say FG an on harder it would depend on how bad. This is just from limited exposure and hope to get more playtime soon.

Thanks for the input about the other scholls concepts polishes. I'll stick with what I got for now until I run out. It could be awhile. I've helped several friends with corrections and can't think of anyone else to help right now. Hmmm...my neighbor down the street called me last week to check out a camaro he just picked up and I haven't been able to check it out yet. Maybe he will have some swirls and scratches that he needs buffed out.

Im a huge fan of FG400, i did a little test spot on a 2010 Dark grey metallic Corolla yesterday (clients) and it finished 100% LSP ready. After an IPA wipedown and multiple inspection lights i couldnt find any evidence of polishing, even on somewhat soft paint.

I also used FG400 on a Jet Black 2007 BMW 335i back in march. I got about 85-90% correction in 2 steps, on a car that was JACKED, i mean a swirled mess. FG400 got everything but the RIDS.

I am VERY interested to try M101 tho, i think it has a bit more cut that FG400. I use a DA and rotary, so im kind of in debate mode as to whether i should order a 32oz FG400 to add to what i have left, or order M101....

Choices...

Here was my latest work with M101. Paired with Optimum Cutting MF discs. I originally had reached for FG400 on this job and had almost no results. M101 cut through it like butter.

Ive now used FG400 and M101. Only on a black car. Id have to do more testing with M101 but from what i can tell FG400 finishes a bit better. Ive used it to one step lighter or metallic colored cars. FG400 on a Medium pad is a killer combo for cut and finish. I want to see how well M101 will do with different pads.

Completely agree with your assessment. FG400 finishes down almost LSP ready on most paints whereas M101 has much more bite, but in most cases needs to be finished down. They both have an important place in my arsenal.

How is M100 different from M101? I have used M105 and thought that was the end of it but now I need to try two more compounds from Meguiars :(

I use FG400, M105, M101 and M100 each has its place. I personally believe M101 on a mf disc
(primed with D300 or Megs Ultimate Compound to aid with dusting)
IMHO M101 does a better cut and finish than FG400.

If needed, I follow with Reflect and I can obtain a nice high gloss 2 step finish on most vehicles.
If nothing else M101 is worth the cost in the quality 1 step finish obtained and the time it saves.

Here's a video comparing M105, M101 and M100

M101 is a true compound in every sense of the word. Its a DEMON CUTTING MACHINE. Literally NOTHING out there can cut more than 85% as much as these "lightning tips in a bottle"


How is M100 different from M101? I have used M105 and thought that was the end of it but now I need to try two more compounds from Meguiars :(

M100 was made to be a mid tier US VOC compliant body shop compound to replace the traditional 3m compound they have been using over a decade. IT has a very long work time and doesnt dust as much as 105.

M101 was originally designed for EUROPEAN aftermarket refinishing. Since the paints are different there as are they polishing methods [they use lower speeds and faster arm passes] the formulation was made for that market. Then, as fat always has it, detailers go a hold of it here and were paying up to $100 for 32oz to ship it here. Then they were screaming at Meg's to release it, and they the rest is history

101 is beefy! M100 I love, such a great all around compound.

^ What he said.

If could only have two compounds/polishes they would be Megs M101 and Carpro Reflect
