The attic will hit R80. Brazelton is doing much of the traditional renovation work himself, with the help of his father and a few friends.

Go with an aluminum patch. Use aluminum rivits or screws. Avoid stainless or other metal screws due to the interaction of different metals. Use a sealant like 3m 5200 or Boatlife. Do not use fiberglass to patch aluminum. It just doesn't hold up well.
Hello Terps! The first step toward repainting your aluminum window casings is to remove existing flake until the loose pieces are completely gone. Then use Phosphoric Etch as a cleaner / etcher to prepare the metal for priming. Use Rust-Oleum Clean Metal Primer as your base coat. It is an interior / exterior rated, oil-base primer intended for use on aluminum. You can use any topcoat over this primer, but I would suggest using one of Rust-Oleum's oil-based paints with the Stops Rust icon on the label.
