Quick tip: Don't just slap a chunk of sandpaper on there and scrape it back and forth with your thumb.
The epoxy will sand much easier than the potmetal, and the potmetal will sand easier than the aluminum.
Which will in turn sand easier than the stainless screws. You'll wind up with waves in your part,
as each material wears at different rates.

Instead, use a block- something stiff to back the sandpaper, so it sands everything equally. For a small part like this, a file works fine.
