McKee's 37 MK37-630480 Iron Remover Combo;

The McKee's 37 Hydro Blue/Xtreme Iron Remover pairs two products that work perfectly together to create stunning reflections and long lasting protection. Xtreme Iron Remover dissolves ferrous (iron containing) particles, leaving your paint squeaky clean and ready for Hydro Blue. It changes colors as it dissolves these particles! Hydro Blue is a spray on, rinse off Nano-coating that blankets your vehicle in an extremely slick, glossy shell of protection. Spray on, rinse off - it's that easy! Each product is a 16 ounce.
