How to remove rust from the car body with your own hands

Rust is a real scourge for cars. The appearance of red marks spoils the appearance of the car, destroys the body and parts. Let’s consider in detail what you can do with them and what preventive measures you can take to prevent the appearance of corrosion. If there is so much rust that you can barely see the body of the car through it, then it is better to recycle the car: https://towingandscrapcarremoval.ca/scrap-car-removal-stouffville.

Prerequisites for rust spots

The phenomenon of corrosion marks is a consequence of the process of metal oxidation. Occurs due to interaction with water, static electricity, air. Rusty spots look unaesthetic and spoil the functionality of the supporting constructions. Causes of corrosion are characterized by the following factors:

The primary cause of occurrence – violation of the integrity of the body coating, small cracks, damage. Water and air get to the metal through them. The more aggressive the environment and the larger the body damage, the more active and faster the corrosion spreads.

The chemicals used in winter on the roads make the corrosion process appear and develop more quickly.

Corrosion spots appear due to the age of the vehicle.

Chips and scratches in the body are another factor in the appearance of rust marks

Too much liquid accumulates inside the vehicle.

Careless attitude of the owner towards the vehicle, neglecting treatment with rust-proofing agents in winter.

The shape and size of the spots directly depend on the above factors. The more spots are visible – the sooner you need to remove them.

Preparing a Car for Corrosion Points Removal

Before proceeding directly to the work on removal, prepare the vehicle. Preparation consists of several steps:

Wash the car, wash the hidden cavities, remove dirt, dust from the body, dry them well. Use specialized car shampoos that provide gentle cleaning and protect the paintwork. Car shampoo must not contain toxic components (phenols, formaldehyde). Dry with a heat fan or in natural conditions.

Inspect the bodywork for damage, cracks, wheel arches, underbody, and the floor inside the cabin.

Options for Removing Rust Marks

What is the best way to remove rust? There are several ways to eliminate rust stains. The most common options are with the help of mechanical and chemical action:

Mechanical method. Concludes in the initial scraping of the places most vulnerable to corrosion. Scrubbing is done with sandpaper. Also possible option of scraping with a metal brush, grinder, sandblaster. Traces are removed to a shiny, clean iron. Then the damaged area is primed and puttyed. The final stage is painting. The mechanical method has certain advantages. It is suitable for removing large amounts of marks, for places with manifested “swelling” of the paint coating, if the rust is strongly penetrated into the metal. The availability and low cost of materials make this method budget-friendly for many vehicle owners. However, not everyone chooses this elimination option because of its labor intensity. The mechanical method is not suitable for places with difficult access.

Chemical method. Concludes in the application of rust converters, which are special reagents. You can buy them in stores that sell auto-cosmetics. The method of using the reagents is simple. The converter is applied to the corrosion spots, which transform into foam after exposure. Apply masking tape around the surface to be treated so as not to spoil the surrounding areas. Foam is easily removed with water or a cloth. A layer suitable for painting may also form over the rust after exposure to the converter. There will be no further spreading of corrosion marks. The chemical method is suitable for hard-to-reach cavities that cannot be treated mechanically. Popular converters, according to experts, are considered “Neutralizer rust VSN-1”, orthophosphoric acid (a component available in modern reagents). Zinc spray, which forms a film for protection, is in great demand.

Painting the affected areas

After completing the anti-corrosion treatment you should immediately cover the surface with a protective material, start painting. Apply a degreasing liquid (acetone, petrol) to the surface before painting. Then it is necessary to apply a base (primer). Paint applied to bare metal will not last long. After the primer dries, the paint can be applied. In advance, take care of the tone paint, varnish, if it is present in the body coating, otherwise the appearance will be unkempt because of the unevenness of the color.
