Dura-Gold 4" Abrasive Filament Nylon Bristle Cup Brush - 5/8" 11 Thread, 1/4" Hex Drill Shank Arbor, Coarse Grit Angle Grinder Brush for Truck Bed Liner Surface Prep, Sanding, Rust & Paint Removal

Excellent addition to the toolbox, cuts down like 320 grit and is perfect for scuffing up areas before primer. I would recommend still going over everything with 320 or a scotch pad before spraying primer. Cuts fast and works well, easy to connect to drill or angle grinder depending what you got. Good value here and seems durable!

Worked very well.

This does a great job on paint, scuffing it up quickly and easily. There appears to be little wear after sanding one long eight foot bed. The only problem is that we had to use it with a drill, since the speed rating is much lower than our 8,000 rpm angle grinder.

What a great product! A must have for preparing to apply a spray on bed liner! It holds up really well and I will definitely use it on many more projects.

I use this on all sorts of stuff. Clean up the frame on a car I was restoring. I used it to clean up a rearend housing for paint and another prior to adding some braces and brackets. Great value. Easy to use. I have mine on a 7 inch variable speed polisher/sander. This doesn't fling the wires off like wire brushes do. Cleans up paint and rust. Works best for me when I turn it slower than at a higher speed.

Using the wheel was nice as it produced the scuff on my trailer that I was wanting. However, after approximately 30 minutes of continuous use, the arbor broke rendering the wheel useless unless I can source a replacement arbor locally.

it worked good for getting the inside of box ready to spray

used it on an engine head gasket. it worked. not too abrasive. seems like it will last for many uses.
