Thats good to hear! And a dremel tool with a sanding head, a die grinder with a grinding stone, some 1200 grit sanding paper, a scotchbrite pad, a brand new red rag, and some wd40. First I scrubbed down the runners with the scotch brite pad, then I wiped them out blew them out with an air tool, and started with the grinding stone. I was very gentle. I rounded out the edges of the runner just to create a smoother transisition for the air, then I started smoothing out the front 1/2 inch of the runner. I then hit it with the dremel tool and sanding head, finished with the 1200 grit sand paper, buffed it to a pollish with a dremel bit with a buffer. Not that the last step was neccesary at all. After every step I scrubbed it again with the scotchbrite pad, the wd40, wiped them out and blew them out again. I made sure everything was as clean as possible. It takes a lot of patience. I probably shouldn't have even used the grinding stone.
