The hood, rear and front doors and front fenders are attached with bolts, so they can be removed and replaced independently. However, when installing, it is necessary to maintain the required gaps, otherwise increased air flow noise will be observed during movement or, for example, the door may knock.
It should also be taken into account 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 with anti-gravel mastic. Closed cavities are filled with wax or foam.
The condition of the body must be checked regularly, otherwise, corrosion of individual sections of the body can lead to severe damage and subsequently to expensive repairs.
Particular attention should be paid to the condition of the underbody, wheel arches, lower part of the engine compartment, as well as body parts hidden under the upholstery.
The car hood is made of aluminum alloy, which requires a special approach to its repair.
Bonnet straightening work requires special tools designed only for working with aluminum. When using a tool that has been in contact with steel parts, there is a risk of aluminum corrosion.
Aluminum protects itself from corrosion by creating a protective film of aluminum oxide, so it is not susceptible to corrosion in the same way as steel parts.
On the other hand, 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 until the bare metal is exposed.
When removing scratches, restore the original 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. Use sandpaper to level the primer layer before painting.
