 SKIN AND FASTENER CORROSION REMOVAL AND CONTROL -
_________________________________________________ CLEANING/PAINTING
_________________
 1.  General_______
 A.  This procedure contains five tasks. The tasks are as follows:
 (1)  
The removal of rust and corrosion

 (2)  
The alodine treatment

 (3)  
The application of the fastener sealant

 (4)  
The application of the corrosion preventive paint.

 B.  The skin and the fastener corrosion control procedures are applicable to the subsequent areas (Fig. 701):
 (1)  
The wing upper inspar surface

 (2)  
The wing-to-body splice areas (upper and lower) that include the fasteners and the splice plates

 (3)  
The lower skin of the wing center section that is a wall of the ram air plenum chamber.

 C.  There are two primer systems. The first system is the MIL-C-8514 wash primer with the MIL-P-8585 zinc chromate primer. The second system is the BMS 10-11, Type 1, and the BMS 10-20 (epoxy) primer.
 (1)  
Chemical paint strippers can remove the MIL-C-8514 wash primer and MIL-P-8585 zinc chromate primer to bare metal (Ref 51-21-11/701).

 (2)  
Chemical paint strippers cannot remove the BMS 10-11, type 1 and BMS 10-20 primers. But, it is not necessary to remove these epoxy primers to bare metal before you can apply the finish coating.
