Optimum tire coat was an absolute nightmare for me. Turned several tires tarnish gold color
I did two sets before the winter, one turned out fine, the other had problems similar to what you describe. I blame the tires, not the product. These were snowflake-on-the-mountain all-seasons, which like to brown. I gave them a good scrubbing but coated them right after, and I guess the cleaning was still pulling brown to the surface.
