I didn't notice metal from doing the crosshatching, but the hone
leaves grit, which is no better.
A good blasting with compressed air around the gap should blow it out.

Sorry, I'm still thinking that honing a cylinder with the piston in is
not a good idea.

Me too, but it ain't my boat and I ain't doing the job.
For all I know he knows a hell of lot more than me about it.
I just wish JR luck and hope all goes well.
Have to keep a positive attitude (-:
