Rupes vs. Flex vs Rotary

**WRAPT C5Z06** · 01-17-2017, 08:20 AM

I currently have a "chinese" 15mm that cost me $120 and it works GREAT!! I use the washer mod. I can get more cut with it using a MF cutting pad than my 3401 with a wool pad. Yes, you have to pay more attention to technique to keep the pad spinning with the 15mm(any non-forced DA), but the cut/finish is just awesome! With the 3401, you could probably get through a detail faster because pad stall is not an issue, but, you will not get as good of cut/finish as a long throw DA. JMO.

Rupes outcuts 3410 it hs proven several times. Rotary on wool is agressive but so is Rupes with the mf. Rotary+foam wont beat Rupes+mf. They are all great machines and each has itd own strenght and minuses.

To me, my first machine a long time ago (over 20 years ago) was a Porter Cable 74something did more for me than the Rupes. Sorry Rupes lovers.
Many of you people that agree that the Rupes stalls, the Flex never stalls and never stalling is working. If you are too scared to use a rotary the Flex 3401 is it and it will never stall.
As I mentioned before in this post Im not here to argue about the machines. Its all about those that are trying to make a choice on which machine.
I would recommend a Rupes to someone that feels they must apply wax with a machine.
I am getting ready to wet sand my white Porsche (orange peel is not bad, will start with 1500) and I am going to see if the Rupes works at that. I have a feeling it will stall at that and hand will be much better but I am going to try

This guy must be a troll lol, i think the same guy trolls in youtube and instagram too lol. Yes you can make Rupes stall buy you can also avoid that with the right technique. I have polished p150 sanding marks with Rupes easily. Also when it comes to Rupes 21, the correction is 70% from the oscilation, so even if you make it stall for split second, it still does correction.

I have all 3 of them and I will say that each has its place in my arsenal.

I do a lot of work at body shops so I do a lot of wet sanded cars. I use Rupes 21 MKII with Megs MF pad and Shine Supply Chop top and it comes out flawless every time.

^^ This is NOT true, believe me! You most certianly can burn paint or strike through with a PCxp, especially on a body line or an edge!!! Ask me how I know...
