My quick build fuselage is largely already alodinded by the factory. Many additional parts to add to the fuselage that are untreated. Have decided to treat them with brush Bonderite M-CR ALCRM 1200. (Hard to get Alodine 1201 bath dip version). So that there is some consistency of treatment. My target is to treat any critical parts and those exposed to the elements, such as torque tube clamps and inspection panels.
Pre-treated with Deoxidine 624 phosphoric acid. Applied the 1200 for 10 min. Even so, the colour didn’t turn out very deep, probably a bit too cold in the workshop.
Like many fellow builders in the UK at present, the empennage will use Aerowave treatment and spray the components.
