I stand by my opinion posted above about tossing the old track and buying new with a small afterthought. I have used Evaporust on my tools to rid them of rust. I was very pleased with it's performance and low toxicity. However, I applied a thin coat of oil on the tools to keep the rust from coming back. The tools I didn't do that.....I got the rust back. Putting oil on track is not going to end well. So, bottom line.....why bother?
