Volkswagen Golf Service & Repair Manual: Corrosion protection for body components, add-on components and welded
components
| |
Wings, doors, covers and flaps must be coated completely on
the inside as well. One wet-in-wet spray pass is adequate for
this. |
| |
Before installing, add-on parts must be sealed with cavity
sealant on the inside in order to restore the original state
→ Chapter „Anti-corrosion materials“. Please refer to
»Vehicle-specific paint information«. |
| |
Vehicles with wheelhousing liners must be provided with
additional scuff protection on the wheel arch
→ Chapter „Corrosion protection measures for wing surface in
contact with wheel housing liner“. |
| |
All welded parts, except the roof, must be fully primed and
surfaced on the inside. The visible inner surfaces must be
coated with one spray pass of base coat and clear coat. This
should be done prior to welding-in where necessary. In cases of
doubt, the series status applies. |
| |
If sealing is required, perform the respective sealing work
after the paintwork structure has been completed. |
| |
Coat all parts that form cavities, such as pillars, braces,
side panels, etc., with cavity sealant
→ Chapter „Anti-corrosion materials“. |
| All series parts which are coated with noise-damping or
anti-chip material (e.g. wheel housing, floor panel, front/rear
cross panels or side member) need to be coated as follows: |
| |
Wheel housings and underbody with sprayable seam seal
→ Chapter „Sealing materials“ |
| |
Use adhesive sealant -D 511 500 A2- as foundation material
to smooth over larger seams and compensate for deeper layers. |
| |
Coat sill panel area, bottom of side panel and corners of
cross panels with anti-chip coating
→ Chapter „Stone chip guard“. |
