I didn't use a hone as I didn't have one small enough to fit the bore.
However the aluminum is quite a soft alloy, so if you do use a hone, make
sure you have the finest grit stones possible, and don't do too much!
Just a light pass to take of the glazing will be enough.
I used a piece of 400 grit sandpaper on the end of my finger and swirled
it inside the bore. I didn't have any pitting problems though.
You can also stick the sandpaper onto a suitably-sized dowel and hone it
that way. Use brake fluid to remove the swarf during and after honing.
