Review on Brush Nylon Filament Thread Max RPM by Edwin White

First of all. DO NOT use this brush with an angle grinder (most are 10,000+ RPM and will completely destroy this brush and make it unwieldy). Inexpensive car buffer for polishing car paint. I got mine from Harbor Freight for $45. The buffers work great because they have adjustable speed settings and strong knobs to hold on to. IMPORTANT: Make sure the buffer has a 5/8 shank so you can unscrew the buffer plate and screw on this brush. This thing has reduced grinding time by about 500% and makes life a breeze! Don't spin it too fast! Sometimes slow speed is better. I sanded the body of the truck as shown in the attached picture in 5 minutes max. Absolutely worth its weight in gold. TL; DR: Buy a cheap 5/8 shank buffer, don't use it with an angle grinder.
