Dura-Gold 2.5 Abrasive Filament Nylon Bristle Cup Brush - Coarse Sanding Scuffing Brush, 14 Hex Drill Shank Arbor - Remove Rust, Corrosion, Paint - Surface Prep for Spray Truck Bed Liner Coatings

This product is a 4" bristle brush that can be used for paint removal, cleaning surfaces with calcium build-up, scuffing paint before applying a spray-on liner, and getting dirt off rusted metal objects. Responding to a question, the manufacturer stated that this bristle brush is not going to hold up well for a sizable surface that requires a lot of paint removal. The 4" bristle brush is rated for a maximum of 8500 rpm. This product doesn't have grit, and they are nylon bristles. Customers have shared mixed experiences with this product. One customer used a 4” wheel in a 5” Milwaukee variable speed set and used up the brush after doing the entire bed of a 99 Tacoma. Another customer used the brush on a wood floor to remove remaining carpet padding that was glued down and mentioned that it wore down after 30 feet. However, a majority of the reviews are positive and recommend this product.
