Marks problem of corrosion on the torque tube for his ailerons might be solved by the use of "rust proof compound L". This was a grease that was developed in the 1940s to prevent the rusting of military supplies sent by boat to the South Pacific. I forget which company made it. It sticks to metal like the proverbial sh*t to a blanket. You can apply it to workshop machines like drill press columns and it will be there years later. It is a grease and as such is a lubricant.
