The procedure for performing operations for corrosion protection of hidden cavities:
1. Install the car on a lift, remove parts and upholstery that prevent access to hidden cavities.
2. Rinse with water at a temperature of 40-50°C through technological and drainage holes hidden cavities (tab. 8-2), bottom of the body, wheel arches until clean water flows out. In this case, the pivoting windows must be closed, the sliding windows must be raised.
3. Remove moisture that has got into the passenger compartment and trunk, blow out all hidden cavities and places where anti-corrosion compounds are applied with compressed air.
4. Drive the vehicle into the rustproofing booth and put it on a lift. Spray anti-corrosion compound in the areas indicated in figures 8-6, 8-7 and 8-8. Processing is carried out at a temperature not lower than plus 15°C.
5. Lower the car from the lift, clean the front surfaces of the body from contamination with a rag soaked in white spirit.
