At the rudder leading edge you're using pop rivets so this piece of advice doesn't really apply. However, when you're putting in an edge break near dimpled holes (think rudder trailing edge), do the break before you dimple.
I did it after and I had a hard time getting the roller tool past each dimple. After I finished I had to re-dimple all of the holes because it flatted them slightly. In the end it worked, but save yourself the extra effort and do the break *before* dimpling.

Pet peeve: "Lose" is the opposite of "find". "Loose" means "not tight".
