Rotary polisher vs duel action polisher, Which is better, quicker, easier, surprising result
HTML-код
- Опубликовано: 29 янв 2021
- I carry out a side by side comparison test of a makita rotary polisher vs a rupes 15mm throw dual action machine. On a very badly scratched and swirled BMW 3 series bonnet, using koch chemie H9 compound and rupes course wool pads,
The results surprised me I’m sure they will also surprise you.
I’d like to do more “myth busting” style videos, what myths would you like to dispel, please comment below

A lot of people in general make the rotary seem like a paint eating demon, like if you touch the paint it will remove it to bare metal.. because they can't use it properly. You don't max out the RPM on a gigantic wool pad and swing it like a maniac with a chainsaw. Instead use slow RPM (1200-1400) and same arm speed as DA, and you'll find that the rotary cuts less than a long throw DA. People are afraid of holograms, which are easier to remove than DA's micro-marring, haze and swirls. If you use a really aggressive pad on a soft paint (sometimes its needed when the paint is heavily damaged) you'll realize that the DA will gouge the paint because of the whipping oscillation motion. Holograms are really shallow, uniform and easy to remove. Those pigtail scratches that DA leaves are way harder to remove, because when the DA goes one way, then it suddenly gets jerked the other, which creates a really sudden movement and acceleration and it makes a relatively deep scratch in the paint. Long throw DA's are way more aggressive than a rotary. I had 15mm and 21mm DA leave same swirls in the paint as if it was never polished, and that was really difficult to refine. Thanks to the uniform and smooth motion of the rotary, it's way easier to work on softer paints without the need of another, gentler machine, because you can drop your RPMs to around 600, lift off the pressure and go from there, while you can't really lower the rpms of the DA by much, because the rotational motion of the pad will stop. Also in my experience, you never can achieve this glass-like look with a DA, the rotary gives a superior finish thanks to how smooth it is. It glides on the paint instead of chopping at it, and that's why paint buffed with a rotary will always have that little something more to it. It's not a huge difference, but i can tell by the feel of the paint and clarity. Also the rotary won't destroy your joints with vibration, cause there is virtually none.
Brilliant video Nic!
The overall finish was stunning 👍🏼
Super brother ..congratulations
Excellent video Nic 👍😎
Thank you.
Enjoyed that!
Thank you
I'm loving the new intro Nic. (you need a mic).
Thanks Chris.
I had a lav mic on but the audio from that was worse than the in camera because it just picked up rustles from my jumper 😩 I’ve tried the lav a few times and it always sounds bad??
great video
Thank you 🙏
Actually fifteen years ago long throw DA machines were only one year away. I began using them in 2007. Well before the Rupes. However Rupes really evolved it. I prefer rotary and forced rotation but I do own a Rupes MK 3 15 as my team in the USA use it. It can do plenty of work and is efficient. A rotary in theory should be faster cutting but not always. But it's very difficult to do one step.
I'm self learnt too and suprising enough I use the same pad and Koch chemie range. But in my experience the rotary is faster but requires more work. Yours looks amazing and really good technique. Any tips on how to keep rotary flat mines a 40 quid rotary weighs a Ton thanks.
Hi Sorry I missed the comment and didn't reply. I think the only tip for keeping it flat is practice! you will find that softer pads and finishing polish is easier to manage the machine than it is with harder pads and cutting compound. so I would practice a bit with the softer pads and then work unto the cutting, once you can keep a heavy cutting pad flat and smooth you will be able to work with anything.
Very informative Nic. Hope you and family are all well. As someone new to machine polishing (finally took the plunge) can you recommend some pads for polishing and correcting? Something for a weekend warrior such as myself.
Thanks mate we are all good thanks. Hope you are keeping well?
Yeah sure I can point you in the right direction. What machine have you got?
Very entry level Vonhaus DA. Got to start somewhere though. 😁
@@l4ckl_621 these Zvizzer pads should be ok for you. I’d say a couple of red ones for cutting and a couple of yellow to finish with. I’m guessing it’s on your bmw? So the paint will be quite hard

Great no BS vid, just what you want. Am in the market for a DA polisher now the next question will be... Do I go 'Forced' or 'Free Spinning!' Thanks buddy!
i have rotary and 2 DA, 12mm and 15 mm orbit. rotary way faster in initial cut but to be honest its need along time to master rotary, when i try DA its very easy to gain same result as some youtuber detailer with same DA.
for car enthusiast is more easy to operate DA
for profesional detailer who used to live with rotary and paint shop worker rotary way better
what i learn again is rotary need less agresive compound than DA for same paint defect.
Thanks for the contact...I guess what I meant was whether I would buy a ''forced DA' with a gear that will not stop under load, (not rotary) of just a 'free spinning' DA like most, that will stop under load... Decisions...Decisions... Cheers!
@@crookassassin i think for easy to handle DA is easier to use, i never use forced DA but now with Microfiber pad, wool pad i dont think Free spinning DA under disadvantage than forced rotation. But if we compare old small and powerless DA like porter cable or m3110 meguiars yes they alot worse than flex3410
sorry I didn't see the comment, thank you. I'm guessing I'm a little late to inform you but if your budget allows I would get a rupes machine or at least something that is the same type of design. these are free spinning with no gears.
@@PrideandPerformance All good, ended up buying a FLEX XPE 80. Small powerful and ‘quiet’. Not cheap at $680 AUD but you can’t go pass the click in click out head. Brilliant!!!
How many times did you go over it?
Each section had 2 or 3 cutting sets.
What are your prices for paint correction?
Hi Howard. We would ideally need to see the car and access what levels of correction are needed to price it accurately. Where about are you based?
Been detailing yachts for 22 years and use both my Makita rotary and a Rupes 15mm, love them both but Rupes will definitely finish better any way you cut it.
If you know how to use a rotary you will finish far far better than any da
The dual action is where it's at now, save rotary for metal polishing, after all how thin is factory clearcoat ? too thin ! and lets not forget that the top part of the clear contains uv inhibitors so it's better to preserve as much of the clear as possible.
Not all the clear coat is the same mix of liquid before applying it? 🤔
My family has been is the paint refinishing business for 40
Years
If you know how to use rotary correctly you can finish far superior to any da
I'm 25 years in bodyshops, you are correct 👍 using a rotary takes a long time to master and is far superior.
Anyone that has the 'da is better' opinion are more often people that dont know how to use a rotary properly
Your both quite right and if you watch the video I’m under the impression the rotary is better too. This was one scenario where the DA was actually faster to the “same” result. No doubting the rotary is a better more versatile machine. I’ve been using one 20 years ish but the modern DA is a far cry from the DA that was available years ago. Basically the DA has continued to improve over the years. The rotary hasn’t really changed
@@PrideandPerformance Fair play to you for the reply 👍 your are right, the DA has improved vastly from what they were.
I guess it depends on what level of polishing is needed, a regular ' bring a shine back' to a faded car or a 'cut and polish' 2 very different things !
If someone has never used a rotary before and wanted to machine polish their car I'd tell them all day long use a DA.
A 1200,2000,3000, cut and polish on a newly painted car for a glass finish, DA just won't cut it !!
Good content though pal, enjoy your videos 👍
@@dbuckley100 thanks mate. I really want to do more videos but I just can’t get used to being in front of a camera 😳 yeah of your bringing back paint that’s been flatted then a rotary is going to have to be used. Also the other advantage of a rotary is when working on tighter areas where a rotary will actually cut faster but a da will stall and not work at all. So it that instance you’ll need multiple da with different size heads etc. this particular job was only going 90-95% correction so surprisingly the da won out
@@PrideandPerformance Yeah I couldn't talk in front of a camera for even 10 secs 😂😂 your doing a good job of it mate 👍 too many videos of lads talking shit about something they know nothing about with 55 purchase links in the description 😂
If you try a 21mm DA, it should be even faster
A DA is a beginner machine!!!!
Polish -> make the car paint even and glossy
Polish-> man from Poland
😬 English is interesting
You dont know how to use a Rotary buffer. You never worked in a body shop. If it takes you 32 minutes to buff half a hood with a rotary you sir cant buff.
it is not bad damage so delete the video ...find a car with hard damage then we will see...this is full of crap
Rotary is by far the best but its for people that know what they are doing people that don't should use D.A..
