You guys might laugh or criticize me but I was at my dad's one day bored watching my little brother and could not leave at the time to get a eraser wheel so I thought to myself what could I make that would be almost the same? I got a drill, 3/4 socket and put some electric tape around! I started real slow cause I was not sure if my homemade wheel was going to work? It worked great you just have to watch when it gets wore out and the sticky part shows though cuz it will leave a little bit of black on the paint. Not saying that I was running it on the paint but did have some stubborn spots! It did not scratch my paint at all. I did wash and wax afterward!
