I reckon that if the Nikasil (which is silicon carbide, after all) can stand the piston rings flying up and down inside it, a few thousand times a minute, for hours on end, a hit of Scotchbrite wont harm it. Whether you can actually deglaze it like an iron/steel bore, I don't actually know. I take advice on that from those on here who know but I'm confident you won't damage Nikasil with Scotchbrite.
I'd always thought that you should leave it strictly alone and if it needed work it was off to the engineering shop for re-plating.
This would suggest for minor abrasions that's not the case

The man certainly sounds like he knows what he's talking about - although I'd be a bit nervous about that Emery cloth, speaking for myself. It occurs to me that, and it's been a long time since I rebuilt such an engine, that I never used to deglaze chromed bores - just get any carbon out. However the fact remains, Scotchbrite won't damage it. We never stop learning. In fact I learn so much, every day, that I sometimes wonder how I've lived this long...

Seems to be what he is saying so just a damn good clean with a ring set will do me.
That's just about spot on
I've run a honing tool down them for a few seconds before before. Didn't seem to harm them.
Did it make any difference? I mean, did it put the nice cross-hatch pattern on it? It would be interesting to get a trashed cylinder and measure it up and see how much comes off it when honed.

Big worry is to make sure you get all the carborundum / emery particles out of the way afterwards....
