That is really quite bad corrosion for aluminium, it's gonna take some prep to get those tubes in a fit state to anodise. If the alloy is not a clean, smooth finish the ano will look awful.
I'd actually be somewhat concerned over the structural integrity of the frame and whether it's worth restoring...
Looking at the pics of the condition of the frame it's a load of stone chips that have removed the anodising and allowed some light oxidation to take place. Structurally it should be fine but it will need some serious cleaning up before it's anodised again.
