Review on 🔸 3M Roloc Bristle Disc Grade 18733 by Dennis Wood

I wish I had known these things a million years ago. Yes you have to be careful to keep moving and not hit your head or block etc but overall very easy and safe to use. Wear decreases over time, which I believe constantly exposes a new layer of shredded material, but the two I received easily outlasted my engine rebuild project. You would think they would be clogged with padding material like regular sandpaper. But that's not the case!
