The bane of owning a car for too long out of attachment or leaving a vehicle unattended for too long is corrosion. An unattended scratch, dent or external damage is sure to cause formation of rust, first where the damage has occurred and then slowly spreads to the surrounding area. In certain climes formation of rust on the surface of the vehicle is much faster, especially when you live in close proximity to the sea, probably due to the high salinity in the atmosphere apart from high moisture. What ever be the reason, it is possible to remove rust from your car surface and prevent rust from happening in the first place to some extent.
How Rust Forms
The Scottsdale Mazda dealership experts emphasized on the fact that the formation of rust occurs when metal is exposed to the atmospheric elements, especially air and moisture, which causes chemical reactions with the metal that cause oxidation. Once rust starts forming on a particular part of the car, more and more of the metal is affected causing the corrosion to spread at an increasing pace till the whole body of the vehicle is covered. The formation of rust intensifies and speeds up with the level of moisture and salinity in the atmosphere. Unpainted, chipped or exposed metal surfaces especially with scratches or dents tend to rust faster. In some cases, you might not notice any externally visible traces of rust and rather you might observe some mild bubbling up of the paint in certain locations. This is an indication that the surface beneath this has begun to rust.
How rust can be removed
Luckily, removal of rust is no complicated process but is quite strenuous and needs some skills you learnt in your school workshop to be renewed. The removal process starts with first properly cleaning out the area using a grease remover. If you have a dent, then you will need to deal with straightening out the dent first.
The next stage involves sandpapering out the affected surface to remove the paint and any traces of the rust. If the rusting is more intense, you might want to get an electric grinder as well to aid your work. When smoothening out the affected area using the sandpaper, it’s a good idea to extend the smoothened area slightly beyond the affected area so as not to leave out any traces as this could restart the rusting process again. During this process if you observe any pits created by the rust, it would be a good idea to use a commercially available body filler to fill the gaps and apply the sandpaper again to smoothen it.
As suggested by the Scottsdale Mazda dealership experts, once you are sure that its ready for painting the first step is to use a rust reformer and a primer which are commercially available as sprays. These will help curtail the formation of rust and ready the section for the next step which is the paint job.
