Rust-proofing a classic car will stop the onset of rust, commonly known as a "cancer" because of the devastating effects it can have on a vehicle if left unchecked. Extra vigilance is necessary to prevent rust from building up on older cars. Classic cars are more vulnerable to rust due to the less advanced paint and body protection that was originally applied to these cars.

Rust will compromise the structural integrity of whatever it is affecting. Rust can go below the paint work, and eat away at areas you cannot see. Therefore, it is important that, particularly with classic cars, they are checked periodically particularly if exposed to environmental conditions, which can initiate the process . For example, salt from snowy roads in the winter will exasserbate the onset of rust.

Rust is a slow, creeping 'disease', so you can successfully treat it to prevent further rust build-up. Surface rust is easily fixed with some good sanding and a proper rust preventative treatment. The benefits of rust-proofing are that it will extend the working life of your car and reduce any costly repair work. Dinitrol rust-proofing products are simple to use and easy to apply. They are effective for up to 4 years depending on the local environmental conditions. Dinitrol does not wash off during cleaning and does not melt or drip in hot weather unlike some other rust proofing products.
