What size honing tool do I need? and what grit?

Theres a slight imperfection on one of the bores (looks like corrosion from water laying in the bore)

I'm hoping a honing tool will remove it.

Thoughts on this?

Your best bet is to take it to a machine shop, place i use will do all the bores with a dangleberry hone (bottle brush hone, glaze braker etc) for ~£30 or a full job for ~£45, Honing is something that is a lot more dependent on the user than the tool and is something even i wont attempt to do at home.

If your in essex Si13's old man runs a machine shop not too far away (somewhere around guilford iirc) might be worth a shot.

Thanks, but I'm gonna give it a go, sounds stupid but I've watched videos on YouTube, I'm only de glazing to remove the slight raised patch from the corrosion, a quick blast up and down should sort it.
