    Hi, nice article. Personally I seal anodised ally’s as opposed to waxing them.
    Wax is too thick or viscous to be able to penetrate into the tiny fissures created by the anodising process.
    What it does do is trap oxygen against and within the surface allowing the oxygen to attack.
    A sealant is far more likely to get into all the pockets and offer better long term protection. This will also be a more discreet protection as opposed a wax that may leave residue due to being applied to a rough surface.
    Heat is also an issue for ally out in the Sun, waxes melt.
    The boat in the picture is of a Smelne (Stevens) 1380 Dutch steel boat.
    The arm, along with the picture belongs to me :)
    Kind regards
