 (1) Treatment of the areas with corrosion
 -Clean the areas with corrosion with CLEANING AGENTS (Material No. 11-002)
 -Make sure that the paint is in the correct condition and mark the area of corrosion
 -Rub the oxidized areas with abrasive paper.
 -Degrease with the CLEANING AGENTS (Material No. 11-003).
 NOTE : The depth of the material removed during the treatment must
____ not change the mechanical strength of the part. If you are not sure, send the part to be repaired.
 (2) Removal of Corrosion - Passivation
 -Apply SPECIAL MATERIALS (Material No. 05-006) with no water with a brush to the areas with corrosion until :
 -the oxide is fully changed
 -it becomes crystalline
 -Apply a protective finish by the DALIC (cadmium plating) or other method.
 NOTE : Apply the paint as soon as possible when the part is dry.

 E. Touching-up Paint that is resistant to Skydrol
 (1) Preparation of the areas to be painted
 (a)
 Clean the surfaces to be painted with CLEANING AGENTS (Material No. 11-002). Dry them with clean, filtered compressed air.

 (b)
 Apply the STRIPPERS (Material No. 12-005) with a paint brush. If it is necessary, use a brush on the surface.

 (c)
 If you do this operation in a building, make sure that the work area is open to the air.

 (d)
 Do not let the material touch the surfaces for more than 5 hours. CAUTION : THE MATERIAL MUST NOT TOUCH RUBBER, PLASTICS OR

_______
 ASSEMBLY AREAS.

 (e)
 Flush with water, under pressure if it is possible until all the paint and cleaning product are removed.

 (f)
 Dry, then clean and degrease with a chlorine-base solvent. Make sure that the surfaces have no oxidation.

 (2) Preparation of the Paint Mixtures
