ceramic coating care

I use Mother's Mag Wheel polish on my TTI's. Works well. I also used Wenol. Don't know if it'll take it all off. TTI recommends that you lay a vapor barrier (plastic) on the garage floor during the winter (cold) season to prevent moisture attacking the ceramic coating. I've been doing this since I installed them, 6 years) and no rust, like yours, is present. Good luck getting it off?
