Dura-Gold6 Piece Abrasive Filament Nylon Bristle Cup Brush Set - 1/4" Hex Drill Shank Arbor, Coarse Grit Angle Grinder Brush for Truck Bed Liner Surface Prep, Sanding, Scuffing, Rust & Paint Removal

just used the 2.5 for the entire truck bed, 90% finished it off already but i still have the other 5 in new conditions, not bad, not bad, good for the steel, aluminum and the old truck bed liner

these worked exceptioally well removing old firewall insulation from our rv and much safer than a wire wheel around the air system hoses

as advertised

As I was getting my garage driveway and pool deck ready for painting, I noticed several areas that black mold was growing where water had collected. Since I had already put in a get deal of work (removing old shrunken sealants out cracks in the concrete, epoxying the cracks and grinding the gloss off the epoxy for painting), I didn't want mold to be a problem after painting.So combining soap & water, a bit of bleach and attaching the cup brush to my battery powered drip, I went to work, expecting to go through at least 2 - 3 brushes for the 50 sq.ft. of work that I had. The brush was terrific. I only used 1 brush and it still looks like its brand new. The concrete surface is clean, the mold is gone, and I left it for a week to see if the mold would come back, and nada.

The media could not be loaded. One of the 3 I used is loose and therefore useless. I bought name brand (I use a lot of Dura Gold products) in order to avoid getting junk. Not really please.

Works great, and good variety of items.

I did the inside of a metal trailer, so I could coat it with a liner paint. Perfect tools.

Does not remove rust easily; they are durable and sturdy but they don't do the job without a lot of work, time and effort.
