Review on 100 Extra Fiberglass Scratch Refills BRS 290 01 - Ultimate Solution for Scratch Removal by Donnie Boss

I have used this type of brush on various rust stains on various metals. It is the only product that completely removes rust. Just be careful and know that fiberglass causes skin irritation. Just ask any grinder/surfboard grinder what fiberglass dust does to your skin. There is a small amount that will come off this stick, but it will eventually remove rust stains. Keep in mind that this product is not intended for removing large amounts of rust, only for touching up small rust spots. Yes, even stainless steel will rust. Also, wear safety goggles and ventilate away from you. This rod comes in a pen holder from the same company. nothing touches the hands. great product and service.
