Paintwork care (BMW 7 Series E32)

Conservation

As necessary, treat the washed and dried car with preservatives to protect the paintwork from water and adverse weather conditions.

Any fuel, oil or brake fluid that gets on the paintwork must be immediately washed off, as they have an adverse effect on the paint.

The application of the preservative should be repeated when water no longer forms beads on the paint or runs off. Regular use of preservatives helps to maintain the gloss of the paintwork.

Another option for preserving paint is to use preservative additives to water. However, they only protect paintwork well when they are added to water at each wash, and washing is done once every 2-3 weeks. You need to use additives that contain wax.

After using detergents, it is recommended to apply a preservative, following the instructions for its use.

Polishing

Polishing of the paintwork is necessary only when the paint has become dull due to insufficient care under the influence of road dust, industrial emissions, sun and rain, and the use of preservatives does not help to restore the shine. It is necessary to avoid using strong grinding or chemically strong agents and it is better to carry out a test polishing on a small area.

Before each polishing, you need to wash the car and dry it thoroughly. When working with polish, you need to follow the instructions for its use.

Do not work on too large an area, so that the polish does not dry out prematurely. Some polishes also have a preservative effect. Do not work in direct sunlight. Do not treat matte parts with preservatives or polishes.

Removal resin stains

Resin stains will quickly become embedded in the paint and will be virtually impossible to remove. Fresh stains can be removed with a cloth soaked in cleaning gasoline. Do not use regular gasoline for the engine. Paint preservative is good for removing resin stains.

Removal insect stains

Insect residue contains substances that can damage the paint layer if not removed immediately. If traces are not removed with water and a sponge, then you should use a soap solution or a detergent solution. There are also special products for removing insects.

Removal splashes of building materials

Traces of building materials (cement, lime and other solutions) should be washed off with a warm solution of detergent. Do not rub too hard, as this can scratch the paint. Then rinse everything with clean water.

Care of plastic parts

Plastic parts, artificial leather seats, headliner, lamp lenses and matt black parts are cleaned with a shampoo solution. Do not wet the headliner too much. If necessary, clean plastic parts with special products. Do not use mineral solvents, gasoline or acetone-based products.

Glass cleaning

Wipe the glass inside and out with a clean damp cloth. If it is very dirty, you can use alcohol, detergent or a special glass cleaner. When cleaning the front glass, also clean the rubber of the windshield wipers.

Note: When using silicone-containing products, do not use brushes, sponges, chamois or rags previously used for paintwork care on glass. When spraying silicone-containing products, cover the glass with paper.

Caring for rubber seals

From time to time, you need to powder the rubber seals with talc or apply a silicone-containing protective agent to them. If you wipe the surfaces of the seals with soap, the creaking and characteristic noises will stop.

Alloy wheels

Alloy wheels need to be protected in the cold season when roads are salted. The wheels need to be cleaned with a jet of steam and then coated with a protective agent.

Seat belts

Seat belts should be cleaned in the installed state with a soap solution, do not use chemicals. Inertia belts should be rolled up when dry. Do not dry belts at temperatures above 80°C or in the sun.

Preservation of the underbody/hidden cavities

The underbody is protected by a PVC coating. Those areas that are exposed to stones flying out from under the wheels (in the wheel arches) additionally protected by mudguards (protective plates). The cavities are treated with special wax or anti-corrosion agents. These cavities are then heated to approximately 180°C so that the composition spreads and evenly covers all surfaces. In addition, some body parts are made of galvanized steel. Before the onset of cold weather, check the condition of the bottom and apply a preservative to damaged areas.

The protrusions on the bottom can collect dust, dirt and sand, and in winter, salt. Therefore, it is necessary to remove these deposits as often as possible.

Preservation of the engine compartment

To prevent corrosion in the front of the car (side members, side members or shields) and parts of the power unit, a special high-quality preservative must be applied to the engine compartment parts, front suspension parts, brake system and steering parts. Naturally, this must be done after washing the engine.

Caution: Before washing the engine or treating it with cleaning agent or steam, cover the generator with a plastic bag.
