The facts about rust and your vehicle

Rust is the common term name for iron oxide to describe the process when iron or a metal containing iron that is weakened due to being exposed to oxygen and moisture for a long period. This process is commonly evident on door hinges, bike chains and padlocks especially when exposed to outdoor weather conditions.

Due to the chassis underbody being out of sight and still under warranty many owners fail to realise that the vehicle is suffering with corrosion damage. The effects of rusting also reduces the life span of mechanical parts including brake and suspension arms whilst causing the vehicle to become less valuable. Many vehicle owners are provided with a false sense of security that they are protected by the manufacturers warranty however this only covers rust damage if a full corroded hole appears in the metal bodywork in the very late final stages of corrosion. DINITROL have over 70 years experience in providing vehicle corrosion protection products.

During the winter months the risk of corrosion damage increases by around 25% due to additional aggravation caused by road salt and moisture exposure. Also many people don’t protect their vehicle due to no rusting being evident. This is a major misunderstanding even when rust is not visible, moisture in the hidden cavity areas of doors, tailgate and body frame is already causing substantial corrosion damage.

Is rust a problem with new modern cars?

Most modern new cars now have a lot of plastic covers fitted around the chassis underbody to reduce wind resistance and improve fuel economy. However large amounts of moist dirt can quickly build up in between the vehicle undercarriage and plastic covers exposing the car to severe corrosion with rust becoming evident. Also due to the plastic covers taking around 17-20 minutes to fully remove the effects of rust are not usually detected when the vehicle is being serviced or MOT checked. New cars are a substantial financial investment and due to the reason we recommend checking your vehicle yourself every year or asking a professional to conduct an inspection, due to corrosion starting from the minute you drive off the car dealership forecourt.

Do you drill holes in the vehicle to access the cavity areas?

Many vehicle models already have pre-drilled holes present that are sealed with a small plastic plug allowing us access. You should not drill any holes into the vehicle to apply products this can weaken the structure and also lead to rusting with bare metal exposed. If appointing a treatment provider to apply the rustproofing applications, we strongly recommend you check and stipulate that they must NOT drill any holes into your vehicle.

Extensive corrosion damage and rust is already evident on my vehicle?

Before applying any vehicle protection applications it’s standard procedure to thoroughly wash the undercarriage chassis area and conduct an inspection for any evident rust and corrosion damage. Any loose rust or corrosion protection coatings from previous treatments must also be removed with a wire brush. You may also need to apply a rust converter containing a complex organic chelat base and epoxy resin that converts rust on substrates into a stable organic iron complex.

How often should my vehicle be retreated?

We recommend that your vehicle should be inspected every year to check for corrosion damage and repair any small areas that have become exposed due to the underbody coating layer becoming damaged from road debris. Also to ensure your vehicle receives the ultimate corrosion protection we recommend a full retreatment every 2 years.
