Hi @fermonica,

Thank you for your question and welcome to the Bunnings Workshop community, it is fantastic to have you with us.

Start by combining cleaning vinegar with warm water. Apply the solution to the corroded section of aluminium and scrub with a toothbrush or Oates Soft Grip Grout Brush to remove as much of the corrosion as possible.

Now the corrosion has been dealt with, I'd suggest using some Rust-Oleum White Flat 2X Ultra Cover Primer Spray Paint inside the corroded section. This is to coat the exposed metal and prevent further corrosion if any water gets in.

Once primed, you can then use Turbo Metal Builders Bog to fill the hole, doing your best to keep everything smooth. Once it has dried, you can sand and paint the bog to match.

Once this is done, I would suggest applying a gap filler such as this Selleys No More Gaps Exterior Gap Filler along the crack between the sliding glass door and the brick. Water getting into this gap is the likely original cause of the corrosion, so preventing further water from getting in is definitely in your best interests.

Let me know if you have any further questions.
