Iron X LS is formulated using the original slow drying Iron X formula you have loved for years. Plus 10% more potency!While the Cherry formula was updated in 2020 the LS formula shown here retains the slow drying formula you always loved. Highly effective, acid-free and pH balanced, CARPRO Iron X stops rust spots and pre-mature failure of the clear coat by making short work of iron contaminant removal across the entire vehicle! Using Iron X saves time and helps avoid the laborious claying process used in traditional car care regimes.This formulation of CARPRO Iron X is safe and effective for use on all car surfaces and will not deteriorate clear coats. This preventative measure puts a stop to pre-mature corrosion.Airborne chemical compounds and ferrous particles (particles containing iron) actually penetrate the paint and create corrosive compounds that eat deep into the paint's sub-layers.
