Maxshine M21 Polisher Review | Pro Results Under $200

[@hammertimee777]

Great video! Lately these Max Shine videos are popping up on my KZbin recommendations, and when I watch it, I always see the same couple of people commenting about why they would pick the Rupes over a Chinese counterfeit company. So out of curiosity, I have did some research into this. First of all, I have found no patent or patent pending on Rupes' polishers technology. If there is no patent for the Rupes polishers, any manufacturer can copy the design and produce it legally. Maybe there exists a patent, but I couldn't find it. The definition of counterfeit is to imitate fraudulently. To call Max Shine a counterfeit is the same as calling the Dewalt, Ryobi, Mastercraft, Makita, Rigid, etc reciprocating saw a counterfeit because the original reciprocating saw was designed by Milwaukee. Also, it is funny that everybody likes to pick on Max Shine. Adam's, Optimum, Griot's, and Chemical Guys all copied the Rupes 15mm and 21mm technology. However, there's absolutely nobody pointing that out. Those companies are selling Chinese made replicas of the Rupes polishers for Rupes prices, and nobody point that out. Also, I have emailed a detailer who own and reviewed these machines. What that person has told me was that the Adam's, Griot's, and Max Shine are identical internally, suggesting that they are highly likely made by the same manufacturer using similar or identical parts. I am by no means saying that I support one brand over the other. I personally have no need for a high performance DA now because I wash my car extremely carefully, as to not induce any swirls or marring. But when it comes time for me to buy a performance 15mm DA polisher, I would buy the Rupes because I am old enough to pay a premium for a slightly better user experience.

Well said!

[@KWW0321]

I wonder if someone used the bench vise with 4 accelerometers attached they could come up with a quantitative value for vibration for comparison purposes. Probably a little OCD though!

[@mback12000]

"Torture test", lol, please. That silliness aside, thanks for a good video.

[@allmight6003]

Super honest video, love it.

[@russelstender8602]

I’ve been looking at the cordless Milwaukee and Flex 18V rotary polishers. Any thoughts or preferences on these 2? Thank you for your Great videos

[@autofanaticcars]

go with the Flex i tried one they are sweet. I have a Metabo 18V for metal polishing and love it, very similar to the Flex

[@collinhopper7542]

I believe the Pro version has some of the features that you'd like to see changed.

[@autofanaticcars]

yes i believe so from viewing it online, they are going to send me one to try out soon.

[@farwes1838]

Thank you I will investigate those models!

[@notfound-qg2ii]

What do you think of the new griots G9 polisher versus the max shine 15 mm Pro? I've seen a lot of good reviews about the griots polisher.

[@autofanaticcars]

watch my full review of it, far super in design, build and engineering with with the 9mm orbit it wont do serious correction unless you use thin microfiber pads and compounds and multiple passes, they are revising their Boss G15 and G21 machines soon they told me.

[@notfound-qg2ii]

@@autofanaticcars interesting you say it will not do correction work because it's a 9 mm! But there have been a few videos already with at doing good correction work. 🤔 😐

[@autofanaticcars]

it depends on the type and paint your working on clearly. i just spent 60hrs on my Shelby GT350R and the G9 was not a machine I was using as i needed much more cutting action for all the sanding and repairs i did.

[@calvinwong365]

@@autofanaticcars would go for G8 instead? For hard to reach areas, headlights?

[@SWAGURA]

I'd still get a rupes over this, infact I compared the m15 pro with the mark3 and the mark3 is alot smoother and the ergonomics is way better. The problem with maxshine that alot of these youtubers fail to mention is that more wattage doest not always equate to efficeny and power, hence why rupes chooses not to play the numbers game, maxshine does NOT utilize the wattage properly compared to the rupes and we all know that waisted power.equates to.heat or vibrations, but for 200 bucks it's a good machine but let's stop with this stupid "it's better than a rupes" argument or the "stalls less" argument aswell.

[@autofanaticcars]

like i said it will get the job done but me personally i would not want to use any DA on a regular basis i just do not like the noise and vibrations from any of the ones on the market today.

[@SWAGURA]

@@autofanaticcars oh no doubt a rotary is superior to any random orbital DA if used properly, it's just that alot of KZbin detailers are trying to make the maxshine into some thing it's not, I've even spoken to an ambassador at maxshine and he even told me there not even trying to make a machine comparable to the rupes because that's way over their budget so idk where people can say it better than a rupes because it stalls less(which is a lie all random orbital da stall, that's how their designed) because of the motor, again it will get the job done and is very budget friendly so let's just leave it at that.

[@autofanaticcars]

yeah the internet is full of funny people, i do not get paid to shoot these videos i do it on my own will and time. i swear if your stalling ANY DA machine your obviously using it wrong and trying too hard to remove defects that is better suited for a forced machine or rotary. I use my flex Rotary often it is so smooth and awesome to use and I also have a few other higher priced machines for solid metal finishing i use for work.

[@UaeDelta]

@@autofanaticcars You know what I did to my DA? Shhh. Bought some upholstery attachment, it does the carpets really well.. :D

[@TheBennynyc2]

Not sure if it’s something your interested in doing as far as a vid. Would love to see how to remove ceramic coating. Thank you for your experience you bring to your vids

[@dylandetails361]

I don't want to spend more than 200-250 dollars all in, including pads and any backing plates, etc. I was looking at the Porter Cable 7424xp, the Meguiars mt300 and the lower end TORQx or whatever it's called from CG. Are any of those worth it? I've been leaning towards the PC because I've heard they are very reliable and well made. Great video as always!

[@autofanaticcars]

Porter Cable as a tool brand was awesome back in the days but now its all imported stuff with not the same level of quality which is why i still have my OLD Porter Cable sanders and grinders. I never ever liked the Porter Cable which is kinda like identical to the Griots 6 inch unit they sell. I would consider this Maxshine and piece together better pads and compounds because when you buy a kit your not getting the best your getting what is cheap enough for them to throw in and still make a profit. I plan on selling this M21 CHEAP for anyone that seriously wants to get into this. I have too many polishers as is.

[@BrownRooster]

Auto Fanatic how cheap you say? Going to send you an email

[@404notfound.....]

Great video! But I'm waiting for the new griots 21mm. 1100 watts of polisher. Life time warranty, and the best part? Coming in at $240

[@crisworkizer]

Nice demo on the MaxShine DA Polisher. I just purchased 3 of them. I'll be dead before they ware out. This just like you said for doing your cars at home 12 times a year, do the math. Good product for the price. Where can I get the roll around seat you have that looks bad ass. Thanks..

[@autofanaticcars]

enjoy and have fun with them, my seat is a modified Griots seat go back on my channel i did a full fabrication video on it for fun.

[@henryhong8863]

Which one do u recommend doing gt350 removing scratches from dealer detail prep?

[@Pepsiaddicto]

What do these actually provide more than any other rotary tool? I paint corrected my Mustang with a $40 10" Ryobi cordless random orbital and achieved excellent results. Took out 2 years of swirls and scratches in a couple hours.

[@j.g.2825]

There customer service sucks. I bought one and it was loud very loud. I called for a refund. They said they would refund for 80% of my money. Lol. I never used it. Polisher came like that.

[@nagonzo]

I’d be interested to see you do a similar review on a harbor freight DA polisher to see if it could be a viable option for amateur detailers

[@autofanaticcars]

im def not reviewing a harbor freight anything there is nothing in that store i ever got that lasted.

[@detailcentral]

I have a harbor freight polisher. It work really well. The effectiveness to me, depends on the pad used for paint correction. I used the harbor freight to polish my motorcycle, truck, and three cars, and it is holding up well.

[@ryancosta8878]

Auto Fanatic I have had my harbor freight DA polisher for years and not one single issue. I also have the Maxshine M15 and so far it’s been great

[@crisworkizer]

Ok Thank you I will.

[@KOSx15]

Which DA would you recommend for me? I’ve been using a torq DA for 2 years now and its such a weak machine. It takes along time to do a pannel because i have to go alot slower for the machine to cut.

[@autofanaticcars]

try one of the new pro maxshines and if you got the dough i like Flex

[@gabea.458]

What is the equivalent value based unit for the Rupes i-Brid Nano long neck? I wouldn't care if it was corded. Does that exist?

[@autofanaticcars]

the best tools of this size and nature are made by Dynabrade, they are air powered, their long neck which i have is not cheap but can run for hours without an issue. look them up they are big in the industrial refinishing markets, all their top end tools are hand made in NY

[@gabea.458]

@@autofanaticcars Thanks for the detailed reply. I would prefer electric or cordless, if I decide on air tools I will definitely give them a look.

[@jalmonte225]

Quick question, what do you recommend to remove Car Pro Hydro2 off a car without polishing

[@autofanaticcars]

Gyeon Prep or Prepsol should do it, use lots of cheap microfiber towels and toss when done.

[@gingionejuice3902]

Would you recommend this over the 6" Griot's Garage D/A polisher? Also, how do you feel about the Scholl Concepts spider pads?

[@autofanaticcars]

yes the 6 inch Griots is the same thing as the Porter Cable never was a fan, much more bang for your buck with one of these Maxshine machines by far and they interchange backing plates and other stuff with more expensive machines.

[@henryhong8863]

I'm looking for quality product so should I go with griots?

[@jdisdetermined]

All depends on your budget and how much you'll be using it. For the most part you get what you pay for, like with everything else. If price is a factor and you're only looking to do moderate correction on your own cars every year or two, you'll be fine with a basic machine. In my personal experience the Harbor Freight polisher is superior to the entry level Griots. It can power through edges, curves, etc. where the Griots stalls very easily. I hated the Griots. If you're looking to detail on some kind of professional level for profit it's a different story. Spend the extra money and get a high end machine. It will save a lot time and pay for itself after a couple jobs. If you're only buying one polisher, I would definitely recommend a gear driven like the Flex 3401. It does not stall and you can efficiently do an entire car with no problem. A long throw needs big flat panels to perform it's best and you'll find yourself needing a 3" machine. Ideally you want to have all 3 to choose from eventually, but the gear driven can efficiently polish the entire vehicle with no problems. 👍✌

[@Nick-qk6ky]

What soap should you reconmend

[@Carlos.Rivera]

On videos before, he recommended CG glossworkz. I use myself and its really good and slick, the wash pad glide over the paint

[@autofanaticcars]

it works good but it actually strips the paint of any sealants and waxes i learned over using it 4-5 times per week.

[@Carlos.Rivera]

@@autofanaticcars snap!! No wonder why you developed your own soap.... any other recommendation?

[@autofanaticcars]

still working on my soap, its not easy to do what I want it to do but we are getting close. i have been using the Griots Boss Surface Wash since last August, works well but not perfect but found it to offer the best self cleaning of any other soap ive tried.

[@Nick-qk6ky]

can’t wait

[@genysmenrunner1677]

Can I use the 3m perfect it series compound and polishes with a DA or a forced rotation like the makita?

[@autofanaticcars]

you def can, but i mainly use the 3M stuff on my bigger rotary tools with the 3M larger pads, works flawless.

[@genysmenrunner1677]

Auto Fanatic all right thanks

[@Carlos.Rivera]

Which pads you chose? Any brand you like?

[@autofanaticcars]

i have so many pads, Griots Boss, Meguiars Pro, 3M, Lake Country, Rupes etc. the pads have a hell of a lot to do with control and vibrations on all these DA machines and I prefer thinner pads on a DA like the Griots Boss Pads.

[@Carlos.Rivera]

@@autofanaticcars i will check em out. Thanks for the reply and suggestions

[@autofanaticcars]

buy a few sample packs and see what you like, for me vibrations are important as i have a hand injury and can not take prolonged stress on my right wrist and hand. also microfiber cutting pads also make these machines much harder to control versus a force driven machine like the Flex 3401 or Rupes Mille, for some reason those are fine with microfiber pads it must be the throw difference

[@GavDetails]

What machine would you use a smaller pad with ? 3-4" pads. And can a smaller backing plate and pad size be used with this tool ( maybe moreso, would you recommend that )

[@autofanaticcars]

for smaller stuff I use my Flex Mini rotary and DA, the Rupes Ibrid Nano Long neck and my Dynabrade air polishers. you may be able to adapt the smaller pads to these larger machines but i would not risk it, i think it will seriously throw the counter balance way off.

[@xMax4541x]

What minimum temperature would you need to be in to do some paint correction?

[@autofanaticcars]

whatever work temps your comfortable in, i do not like to work below 50 degrees for personal comfort reasons of being outside or in the garage doing these jobs over a long period of time.

[@GRJCLyon]

I think we can all agree that a polisher had no business being applied to that red paint. It didn't need it. LOL

[@farwes1838]

Good review AF. I am new to doing this type of detailing myself since I bought my GT 350. I have always been a big cordless tool guy myself and wanted to know if there is an adequate cordless polisher out there you would consider?

[@autofanaticcars]

Flex makes nice ones as well as Metabo but they are not cheap. I have two Metabos for metal finishing when I go on the road and they work great, awesome not having a cord.

[@SlingbladeJim]

Don't they make a laser device that measures surface heat instead of looking stupid and having to touch the machine every 10 seconds........................

[@bobcarr2464]

Where to buy for under $200 ?

[@autofanaticcars]

Buy a Griots Boss G9, or G15 best deal and warranty on the market today

[@UaeDelta]

How heavy is it compared to the Flex 3401 bro?

[@autofanaticcars]

hmm i think there feel about the same in weight, around 4.8lbs or so the 3401 is a touch shorter in length

[@Themazcorner]

Do they have anything similar to Rupes LHR75?

[@autofanaticcars]

i have so many machines for various jobs but mostly solid surface refinishing which i do not show since it does not pertain to car detailing and they are very expensive

[@Themazcorner]

@@autofanaticcars was thinking if Maxshine did have a similar product to the LHR75E

[@autofanaticcars]

they are sending me some of their newer machines for me to test and if i like them il shoot videos on them all so stay tuned.

[@Themazcorner]

@@autofanaticcars great, I am really close to pull the trigger on the 75...

[@kevinbrady75]

do a torture test on a harbor freight orbital tool

[@SteveManCentral]

Why not fill up your own gas? Good video though, just confused on that part.

[@autofanaticcars]

many stations do not allow you to in NY thats why, same in NJ

[@SteveManCentral]

@@autofanaticcars Really?! That's weird. I've never heard of that. Do you know why that is?

[@SWAGURA]

@@autofanaticcars really? because here in queens we still can pump our own gas.

[@pulledofftheroad]

SteveMan Central Oregon and NJ have state laws that prohibit you from pumping your own gas. When I go back home to visit (Oregon), I hate getting gas because you have to sit there and wait for the worker to come and do it.

[@neorg89]

I got a chemical guys I’m not sure if is a good one

[@daves.3278]

Same i got the Torq Q , FX and the 22D they last a long time so yeah good polishers 💪 the 22D is the best if you want heavy correction

[@darkman8022]

No one pumps my fuel

[@platinumautoglasswindowtin88]

Then you won't get gas in Oregon

[@EVERYDAYLAWNCARE]

What would be the price sir ?

[@matthewfranzen4593]

Im VERY interested in purchasing this polisher from you!!!!! Please contact me!
