Sealing of the body is ensured by the use of various rubber seals (see fig. Rubber seals), sealing mastics, rubber plugs for technological holes and careful fitting of mating parts.
When removing or installing seals with metal frames, do not allow the frame to wrinkle and corrugations form on the seals.
When installing door opening seals, apply 88-NP-35 glue under the seals from the upper edge of the rear wing along the top of the door openings and along the central pillar to the door sills.
After installing the doors at the corners of the hinges, apply sealing mastic 51-Г-7, as shown in fig. Places for applying sealing mastic in doorways. When replacing or rearranging doorway seals, apply sealing mastic 51-G-7 to the upper corners of the central pillars.
Seams of resistance spot welding, which are welded to stamped body parts, do not give a tight connection. They are subject to intense corrosion, especially on bends of sheets with small rounding radii and in places of metal overstress.
From moisture and dirt, the welds at the car factory are sealed with D-4A plastisol.
When replacing individual parts of the body, after welding and applying the primer, coat the welds on both sides with D-4A plastisol and apply non-drying mastic 52-G-7 into the corner joints in the places shown in Fig. Welds and joints to which sealing mastic is applied (body view on the left), pic.
