Review on 🔸 3M Roloc Bristle Disc Grade 18733 by Rui Knain

I bought it on YouTube recommendation to clean engine mating surfaces. This is a tool for the job. I cannot tell you how many surfaces and time has been spent cleaning surfaces so carefully with razor blades and scrapers. You must really try to damage the surface with it. I bought 4 to make the motor and ended up only needing 1 so they work well too.
