Rupes 21 polisher, ISSUE!!!!!!!!?????????

[VickiSue97b]

I bought a Rupes 15 and used it this weekend on a pristine audi tt, and wasted about an hour trying to figure out if the backing plate was coming apart or the machine was going to catch on fire. Black shreds all over the car and it did not improve at all. Seemed less noticeable on the vertical panels than the horizontal. If it breaks in then fine, otherwise I'll be getting the washer. All this rubbing has to be limiting the correction power of the machine. Not happy...

I have used the rupes 21 and the mini and find that I have not had this issue. Granted have only used these on 2 cars, but I find that as a "newbie" the rupes 21 is extremely easy to use and control and is a great machine. The mini seems a be a bit more of a 'tempestuous child', harder to control, when compared to the 21. but still a great product. I'm not a fanboy, just really like and appreciate the machines for helping me in providing my rides with a great finish.

I have the same issue with mine. On another thread they said to put Vaseline on it. I'm so thinking the washer would fix the probem.

Washer mod should solve that

The RUPES BigFoot Polishers feature an anti-spin shroud that should be lubricated after use. This keeps friction between the shroud and backing plate from wearing away the shroud quickly.

We recommend dielectric grease, although Vaseline will work in a pinch.

If the shroud does wear away, it will disable the Anti-Spin from working. While this may increase pad rotation slightly when engaged to the paint, the biggest difference you will notice is the pad will rotate in free air much faster.

I have the Rupes 15 polisher and I also noticed some black flecks when I first used it. It cleared up rather quickly and has been fine since. I would say by about halfway through the first car it stopped. I did not do the KB washer modification that many here recommend. I found that using good technique and absorbing the learning curve on the Rupes machine was all that was needed. So far I don't feel it is necessary.

+1, and I didn't do the KB washer mod as well. I'm drooling for a MKII though

Mine did the same, especially after cleaning the lubricant out of the shroud.

Oops!

It will spin without the washer, as if it has the washer installed.

I have a new on the way though, I liked how it ran with the anti-spin shroud intact, believe it or not. I had some issues initially, but got the hang of it.

The Griot's G21 includes lubricant with the machine, take note

not to mention a washer and being able to switch backing plates with no adverse effects as well...

As a tool that seems to be primarily marketed for use by professionals and knowledgeable DIYers, why has Rupes decided to include such a thing as an "anti-spin" feature? There seems to be no benefit that I can think of other than protecting an inexperienced user from slinging product by lifting the pad while at full throttle.
