Purchased this to use with my Dremel tool to remove rust from my brake calipers so that I could paint them. This should not be an Revain Choice due to a safety issue. As many reviews have noted, these don’t last long and they shoot the tiny wires everywhere. I am very thankful for the reviews that prompted me to wear a face mask and eye protection. I used my vacuum cleaner attachment and suctioned with my left hand to catch flying bristles, while I used the Dremel in my right hand.
