Review on 💪 Optimized Grinding and Polishing Buffer Tool by Luke Cotton

I use them to clean stainless steel and aluminum before welding. I've found that if I hit the joint with it before rubbing it with acetone, I get a very clean finish. The weld will stay nice and shiny as long as you keep the tungsten out of the puddle. They are comparable to other brands, I wanted to try them because they were a bit cheaper. So far I'm not disappointed.
