rupes mark II 21" vs 15"

[Dan Tran]

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.

To be fair its only his that stalls that bad, none of my polishers do that, does your 15ES do that? If not, worry not.

Mine doesn't do that with the white Rupes pad.

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.

[Zubair]

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.

... 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.

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
