Was looking for something to push with a car to be able to polish up the rails. Couldn't find anything so decided to make one. I am using 3M red metal finishing pad to polish the rails with 2 10mm diameter magnets to hold it down. There are two 2.5mm holes behind the magnets If you want to thread them to remove the magnets. Have any questions please let me know. Happy racing!
