Ideas a builder, maker or community group could start on:

  1. A kit containing nylon washers, rubber gaskets, and plastic-coated bolts specifically designed to isolate steel hardware from aluminum surfaces.
  2. A mobile app or web tool that allows users to input two materials and provides a compatibility rating and a list of necessary isolation materials.
  3. A standardized guide or template for shed owners detailing the specific anti-corrosion coatings or barrier materials required for common metal-to-metal exterior attachments.

β€œI am afraid of aluminum corrosion when attaching other metals to that door. ... Do I need to do something with the holes that I am about to drill into the door or am I just paranoid about the possible corrosion?”
