The hood, rear and front doors and front fenders are bolted on so they can be removed and replaced by yourself. However, during installation, it is imperative to observe the necessary clearances, otherwise increased air flow noises will be observed during movement or, for example, a door may knock.
It should also be borne in mind that in order to improve the tightness of the body, the joints of the parts must be properly sealed.
The bottom of the car is additionally protected by anti-gravel mastic. Closed cavities are filled with wax or foam.
Checking the condition of the body should be carried out regularly, otherwise, the corrosion of individual sections of the body can lead to severe damage to it and in the future to costly repairs.
You should especially monitor the condition of the bottom, wheel arches, the lower part of the engine compartment, as well as body parts hidden under the upholstery.
The hood of the car is made of aluminum alloy, which requires a special approach to its repair.
The hood straightening work requires special tools designed only for working with aluminium. When using a tool that has been in contact with steel parts, there is a possibility of aluminum corrosion.
Aluminum self-protects against corrosion by creating a protective film of aluminum oxide, so it does not corrode in the same way that steel parts do.
On the other hand, the so-called filiform corrosion caused by the destruction of the paint layer can develop due to the effect of electrolysis on the aluminum surface. Since surface cleaning accelerates this corrosion, it is necessary to limit the cleaning of the hood to a minimum to expose bare metal.
When removing scratches, restore the initial primer and then apply a chromophosphate compound to ensure good adhesion of the paint layer.
To level the surface and protect it, apply a two-component primer in the required area. Align the primer layer before painting with sandpaper.
