In view of use of difficult processing equipment and need of high-quality performance of work processing of the hidden cavities is recommended to be carried out only at service stations of cars.

Before works install the car on the elevator, remove the details and an upholstery interfering access to the hidden cavities. Wash out the water heated to temperature of 0-50 °C through technological and drainage openings the hidden cavities (tab. 8.2) and a bottom of a body to a pure effluence. At the same time lowering glasses of doors have to be lifted. Remove the moisture which got to salon and the luggage compartment, blow compressed air all places of drawing anticorrosive structures.

Hidden cavities of a body (front view): 1 – average cross-piece of a floor; 2 – back cross-piece of a floor; 3 – back longerons of a floor; 4 – connectors of sidewalls and front; 5 – cowl pockets; 6 – top amplifiers of mudguards; 7 – lower cross-piece of a frame of a radiator; 8 – forward amplifiers of mudguards; 9 – forward longerons; 10 – floor thresholds

Hidden cavities of a body (rear view): 1 – lower surfaces of pockets of doors; 2 – floor thresholds; 3 – forward connectors of thresholds of a floor; 4 – a cavity between a guard of a front and a floor; 5 – cavities of forward longerons of a floor; 6 – cavities between mudguards and amplifiers of forward racks; 7 – cavities between external and internal panels of sidewalls; 8 – back longerons

Fig. 8.10. Hidden cavities of a body (bottom view in front): 1 – lower cross-piece of a frame of a radiator; 2 – a cavity between a guard of a front and a floor; 3 – forward longerons of a floor; 4 – cavity of a forward connector of a threshold of a floor; 5 – floor thresholds; 6 – back cross-piece of a floor

Overtake the car in the camera, put on the elevator. Put with dispersion anticorrosive structure to the places shown in fig. 8.8,8.9, 8.10.

Lower the car from the elevator, clear of pollution front surfaces of a body the rags moistened in white spirit.
