6 Cup Brush, Nylon Filament, 5/8-11 Thread, 2500 max.RPM

Very effective at scuffing paint. Perfect for prepping a truck bed for spray on liner. Not good for a high rpm tool (like a single speed 10,000 rpm angle grinder for instance - way too aggressive and cant be controlled). Get an adaptor and use it with your drill.

Took the paint right off!

This will remove paint to bare metal quick so is time saver

It melts slowly and will leave a film on whatever your trying to scuff up

EXCELLENT 100%

Works as intended

You you make sure your speed is set for slow it will work nice taking the shine off of trailer or truck bed to get ready for spray on bed liner. If you try to run this fast it will go bad in just a few mins.

great tool

First things first..do NOT use this brush with an angle grinder (most are 10,000+ rpm and will absolutely destroy this brush and be impossible to handle) I went out and got a cheap automotive buffer meant for buffing car paint. I got mine from Harbor Freight for $45. Buffers work great because they have variable speed settings, and they have sturdy grips to hold on to. IMPORTANT: Make sure the buffer has a 5/8 shank so that you can unscrew the buffer pad and screw on this brush. This thing cut down my sanding time by like 500% and it makes life a breeze! Dont spin it too fast! Sometimes slower speed setting the best. I sanded the bed of the truck in the attached picture in about 5 minutes tops. Absolutely worth its weight in gold. TL;DR: Buy a cheap buffer with 5/8 shank, dont use this with an angle grinder.

I purchased this to use on wood to remove old finishes, although it did do that pretty well, it would have been better if it contained some engrained abrasives to help with the job. For the price it will work and has held up fairly well during this testing. I do understand this is not what it was advertised as the primary use, so I am not disappointed with the product.
