Processing instructions for cavity preservation agent

AP97.20-S-0640-01S

Apply wax from inside in crosshatched areas following sealing and paintwork, however, before performing assembly work.

 Insert spray hoses as far as possible into hollow cavities.
Spray while inserting and pulling out slowly.

Carry out repair preservation twice successively with a flash-off time of 5 min between the processes.

 The spraying hose should be stiff and the nozzles should spray at angle to the front and rear.
The cavities should be dry.

After drying, ensure that drain holes are not plugged.

 The processing temperature should not be less than +15°C.
Additional preservation measures may be required, depending on the repair area, deviating from the standard cavity preservation shown.

Rivets that are not sealed with seam sealant must be treated with wax.
