Etch and Alodine in Hangar A, Control Columns in Hangar B

Part of the preparation of bare aluminum for painting is the "etch and Alodine" process. Etching cleans the aluminum of surface contaminants. Alodine helps protect aluminum from corrosion and also increases the ability of paint to adhere to the metal surface. Once the etch and Alodine process is completed the components, in this case the wings from the Moody 182, will be ready to shoot with primer.

Ian and Terry completed the etch yesterday.

Terry applies the Alodine which typically remains
on the aluminum for three to five minutes.

Ian rinses the Alodine from the wings.

In Hangar B, Chuck installs the control columns in the 182.
