3+ vital steps to undercarriage rust prevention of car

When oxygen comes into contact with iron it causes rust. Today, metal objects susceptible to corrosion have a rust prevention paint applied to it as part of the manufacture process. If rust takes hold it spreads very quickly and can affect it's integrity and safety. During car manufacture all metal parts are painted including the undercarriage to protect it against corrosion. Car's that leave the production line have sufficient rust protection to last at least the first five years, which generally covers the duration of the warranty period.

The undercarriage of a car is prone to having the paint work chipped. Cars that are frequently driven 'off-road' over gravel terrain and on roads that use salt to de-ice during the winter months increase the risks of damage to the rust protective layer of the undercarriage. The paint chips and exposed metal is left vulnerable to salt and water creeping in and, combined with air, starts the corrosive process. Rust formation affects the integrity of a car and, if not dealt with will eventually become an expensive repair job. So, follow these steps to more positive outcomes!

  • Wash car regularly, particularly during the winter months paying attention to the undercarriage (often forgotten - a case of 'out of site, out of mind!
  • Apply a rubberised undercoating
  • Inspect the undercarriage for chips or rust spots
  • Treat rust as soon as possible with a rust converter 

If, on inspection rust is detected on the undercarriage, here is the advice offered by many auto specialists:

  • remove all loose and flacking rust particles with a stiff bristled wire brush - it is important not to scrape away all traces of rust for the rust converter to be effective. The rust converter works by chemically bonding to the rust and sealing it in.
  • degrease and wash the area. Then wait for it to dry thoroughly. This step ensures that no surface contaminants will interfere with the reaction of the rust converter on the rusted surface.
  • use a brush to apply the rust converter
