When only the Ñ-11Ä plastisol coating is affected, while the
primer is intact, scour any dirt from the relevant areas, then on a
dry surface apply Åèå-1-type plastisol by means of a brush or
airless spray (1.5 mm thick). Allow to dry at ambient temperature
within a day or at 90°ë within 30 minutes.
In the event of major damages of protective layers and dam-
aged primer, clean of dirt and rust the area affected to the bare
metal, then apply Éî-073-type primer on a dry degreased sur-
face. Using a brush, apply Åèå-1-type sealant on the areas pre-
pared.
When the vehicle is in use no longer than 1-1.5 years, it is
recommended to have a minimum overlapping of a new sealant
over an old layer. In the event of a longer field service with this
underbody protection, apply the sealant over the entire under-
body and wheel arches surfaces.
In cold weather before use, store sealant paste in a warm
room to warm it up to at least 20°ë. When thick, thin sealant with
ksylol to 3% as a maximum. Clean the paintwork of excessive
sealant using a cleaning cloth moistened in white spirit.
Body - sealing and tightness
The body tightness is ensured by use of rubber seals (Fig.8-
9), pastes, bodyfillers, sealants, rubber plugs in provisional holes
and thorough levelling of adjoining parts.
When removing or refitting seals with metal reinforcement,
take care not to crumple the metal frame or seal.
Weld seams do not offer an absolute tightness between the
parts, so corrosion is encouraged when water or moisture gets in
between the welded parts. Use Ñ-4Ä-type plastisol on weld
seams to guard off moisture and dirt; apply the 51-É-7 wet-type
sealant (Fig.8-10 and Fig.8-11) on angle joints and clearances:
- between the sidesills and bulkhead (passenger compart-
ment side);
- between the bulkhead and front pillar panel and battery tray;
- between the front chassis arms and radiator support / bulk-
head;
- between the bulkhead and front cover plate;
- between the rear floor / rear floor extensions and rear wheel
arches, bodysides and rear end cross-member.
