I tried applying greaseless compound to my 8” 3600 RPM buffer. At such speed the compound would not stay on the wheel, or adhere in the first place. I’m now in the market for a lower speed machine. However, I’ve been surprised at how expensive the lower speed machines are. I’m not really interested in spending $200+ on a replacement buffing machine. I like the price of something like this, but I suspect that the quality may be low (and may not be big enough). In any event, I’m looking for a recommendation for a reasonably priced buffer. Thanks a million!
