Today I managed to get all of the rear fuselage rib parts alodined. My Aluprep solution had gone off & was ineffective so I mixed a new 12 litre batch, I also added a gram or two of Alodine powder to the existing bath just to refresh it a little. Hopefully I'll be able to borrow PGC's long alodine baths over the next couple of days so I can alodine the longerons.
