For 1986 model year, the body assembly of all Audi 5000 vehicles will be galvanized.

Special precautions must be followed when welding or refinishing.

Welding

Spot welding

- weld current must be increased by 10 to 30%
^ select highest possible electrode pressure

MIG welding

- work area must be ground clean

WARNING

Fumes from welding galvanized sheet metal contain TOXIC OXIDE of ZINC. The zinc fumes, as well as the smoke from burnt paint and undercoating MUST be vented from workplace.

INSURE PROPER VENTILATION

Preparation of refinishing area

Work sequence

- coat welded areas with zinc spray or cold zinc paint
- prime with zinchromatic primer/filler or selfetching primer such as Dupont 6155, 6165 or equivalent

Note

On spare parts, grind black finish lightly, do not damage zinc coating
^ wet sand scratches with 360-400 grit paper
^ use filler on dents

CAUTION

After grinding black finish down to zinc metal do NOT allow filler to contact other black finish areas. A flaw will result in finish coat.

- proceed with normal refinishing methods
