rupes mark II 21" vs 15"

Zubair said:
... The 21 MKII is ridiculous in correction just like a rotary and should come with a warning, not because it will burn paint but because it removes paint unlike any dual action in existence.

Hey Zubair. I'm curious as to what you're using as far as pads and polishes go to get that insane paint correction. I just picked up a 21 mkII, but haven't played with it much.

Precisely why I don't take opinions on this forum by people who don't own all as they only know what they own and rave about it without knowing theres better out there...much better...

There is truth to that. And in the end, it becomes so subjective as individuals have their own preferences. Me, I don't care too much for the soft start of the Rupes 21. And that's just my own personal preference :)

Question is what don't I use. I think I own and use almost everything available to me and the list is over 120 products on last stock take so won't bother listing them. What I will state is no matter what I've tried I keep returning to Menzerna and CarPro. As for pads everything I bought from AG has not disappointed but what really stands out has been BnS/GG Boss pads. They cut better and are way more durable than the Rupes pads.
I hope Rupes can spend a day at BnS, if you reading this Rupes don't hate the truth.
 
I totally agree with zubair that 21 mk2 is a beast and outpowers 15 mk2 easily.

I'm gonna return the MK II 15(haven't opened it yet) and go with the MK II 21 with a 5" backing plate. Go big or go home. :dblthumb2:

Just to be clear, the 15 MKII is still more powerful than any other dual action out there, long throw, forced rotation etc. included. It just takes second place behind the 21 MKII which is the new unrivaled king of ultimate paint correction.
 
Why do I insist on reading these threads? Now I wish I got the 21 MK II from the beginning vs. the 15 MK II.

Lol.

I promised myself not to buy the 21 until my current 15 goes down in flames. Which it won't anytime soon...

:: sad face ::

Dear newbies,

Don't purchase anything until you receive great feedback from people like found here who actually have tried both these options.

Don't be like me who makes poor emotional purchases.

@ Dan, you didn't make a poor decision. How are you finding the paint correction on the 15 MKII? Don't you love how it handles? Particularly how smooth and maneuverable it is?
 
Ps: the 15 MK II still is enjoyable to use. It fulfills its function. I just happen to suffer from "Tim The Tool-man Taylor" syndrome. Aka bigger is better.

Anyway, enough about me :: awkward laugh ::

Zubair, the truth is I really do LOVE my 15 MK II. It truly is a remarkable machine.

I went through a period where it was purely user error.

But NOW... I have my technique tightened up and it's super smooth.

Great to hear as I too love my 15 MKII and think its the most balanced of all my tools. I even nicknamed it "The All-Rounder" because of its smoothness, balanced nature and versatility.
 
Actually now that I think about it, I went with Mike Phillips' recommendation straight from his book I believe.

It mentions "Box stock recommendation — start with the Rupes Bigfoot 15" if you want to purchase one Rupes polished that will tackle a wide range of detailing projects.

It was all I can afford at the time so I when with the 15 as a happy medium.

I'm sure it would have been a 21 plus a mini had the money been available at the time.

His must of been defective or something, I have the MKII 15 and it only stalls if used incorrectly.
 
Zubair mentioned earlier that a 15mm, generally speaking, won't rotate the pad as good as the 21mm. This was the case with the BOSS polishers as well. I had both the 15 and 21 BOSS polishers. They both had the same motor, but the 21 had much more pad rotating power than the 15. I think a lot of it has to do with momentum alone of the 21mm helping the pad rotate better. KB once told me this. Plus, I have a feeling I would always have to use speed 6 with the MK II 15, and could probably get away with speed 4 on the MK II 21. The 5" BP on the 21 would make it WAY more versatile it seems.

Thats correct, can't change the laws of physics, the longer throw keeps rotation better than the 15's higher speeds. What proves this further is speeds 1-4 between the two machines speeds are almost identical but the 21 is way more powerful at those lower speeds. At higher speeds 5-6 the gap narrows but still in favour of the 21.

Very good info! I just ordered the MK II 21 with a 5" BP. I'm returning the MK II 15. As far as a DA for tighter areas, I don't feel the need for the Rupes Mini. My GG 6" with a 3" BP works perfect.
 
That GG6 850W (DAS 6 Pro)with a 3" and 5" bp is a performance bargain. I would go as far as to say from all polishers its the best bang for the buck. GG6 + Rupes 21 MKII, no need for anything else. I've been struggling to get stock of the DAS 6 Pro as everyone is sold out for months and I can't pick up a GG6 because its 110V.

Thanks for the reply. So far, my limited experience with the GG BOSS pads is good. I tried the BnS Low Pros (?) and also liked them.

Spend a day at BnS....pretty funny. But I've seen enough comments about Rupes pads not lasting very long
