A commonly used term, iron fallout typically comprises of ferrous metals that are charge attracted to the vehicle’s surface and become embedded once in contact. Iron fallout can occur from a number of sources including heavy industrial works, railway works and brake dust from your vehicle itself. These sharp & sometimes extremely hot particles embed themselves deep into soft surfaces on the vehicle and begin to oxidise. This oxidisation process is of a particular threat as ferrous metals expand when oxidising. This expanding reaction can be very damaging and cause blistering underneath the painted surface and even initiate oxidisation of the surface of the vehicle itself in worst cases.
