I've heard tons of times about borimg out a "used" cylinder. I get what you do when you bore it, but I was wondering if it can be done to a Nikasil cylinder...can someone bore it 0.5mm, and it all ends here? or do I have to do the Nikasil again?
Does rebore work fine only for sleeves?

I'm having a hard time with this...any input on it is great.
