(3) Do these steps to remove corrosion from resisting steels (all types), nickle-base alloys and titanium:
WARNING:_______REMOVE ALL SMALL PARTICLES OF TITANIUM ALLOY. THE TITANIUM PARTICLES CAN EASILY IGNITE AND CAUSE A FIRE. EXTINGUISH SUCH FIRES WITH DRY TALC, CALCIUM CARBONATE, SAND OR GRAPHITE. DO NOT USE WATER, CARBON DIOXIDE, CARBON TETRACHLORIDE, OR AN ORDINARY CHEMICAL FIRE EXTINGUISHER. INJURY AND DAMAGE CAN OCCUR IF YOU DO NOT REMOVE ALL TITANIUM PARTICLES.
CAUTION: PUT COVERS ON ALL ADJACENT AREAS THAT DO NOT HAVE
_______ CORROSION. THE CORROSION REMOVAL PROCEDURES CAN CAUSE DAMAGE TO AREAS WITHOUT PROTECTION.
(a) Use a stainless steel wool, a wire brush, abrasive paper or sandblast equipment to remove corrosion.
NOTE: Make sure you remove all the corrosion on the surface.

ALODINE COATING - CLEANING/PAINTING
___________________________________
1. General_______
A. This procedure contains two tasks:
(1)
The first task is to apply Alodine 1000 solution.
(2)
The second task is to apply Alodine 600, 1200 or 1200S solution.
B. Alodine is used for protection. It is a paint base. Alodine 600, 1000, 1200, and 1200S, solutions are used to give the chemical coating.
C. In areas where Alodine may come in contact with BMS 10-20 primer only Alodine 600 should be used. BMS 10-20 is typically used on the fuel tank wing structure.
D. When you use Alodine 600, 1000, 1200, and 1200S obey the precautions for chemicals that can cause corrosion. Wear respirators and rubber or neoprene gloves when you mix and apply Alodine solutions. Follow the necessary precautions and do not get Alodine solutions on your skin.
E. Do not let the papers or cloths dry after you apply Alodine solutions. They can cause a fire when they are dry. After you use the cloths or paper, soak them in water before you discard them.
