When it comes to paint decontamination, most cars we see have never had any sort of decontamination since the owners had the car. We start off with an iron remover. This gets rid of any sort of iron particles, brake dust, or industrial fallout sitting on your paint. When the chemical reacts with these contaminants, it turns purple. Most cars are FILLED with these type of contaminants and the owner is unaware. These type of contaminants will cause rusting, oxidation, and ultimately paint failure.
