 D. Apply the Corrosion Preventive Paint (BMS10-100)
 S 377-022
 (1)  Shake the mixture by hand or power mix for 10 to 15 minutes. The aluminum pigment must be fully mixed.
 NOTE: Do not get air bubbles in the mixture.
____ If it is necessary, you can add C25/90S thinner to make the mixture thin (up to 20 percent, by volume, of the base)
 The working life of the material is 8 hours.
 S 377-023
 (2)  
If it is necessary, rework the BMS 10-11 and BMS 10-20 primed surfaces. Let the primer dry before you apply the corrosion inhibiting finish (AMM 51-24-11/701).

 S 377-024

 (3)
Put the mixture through a clean cloth filter before you use it.

 S 377-025

 (4)  
Apply the mixture with a spray gun until you have a dry layer with a thickness of 2 to 3 mils.

 NOTE: If you get a dry spray condition with BMS10-100 you can
____ decrease the atomizing pressure or you can make the mixture thin with C25/90S thinner.
 (a)  Allow each layer to dry for a minimum of 30 minutes.
 S 377-026
 (5)  Let the topcoat air dry at 65 to 85°F for a minimum of 4 hours before you move the material. Let the material dry for 24 hours before you use the material.
 NOTE: You can use heat on the surface to decrease the cure time.
____ Increase the temperature of the surface to 125 |5°F for 2 hours.
