Mirror repolish

I posted this in an ongoing thread in the Equipment section but got no response so I'll ask here where it's probably more relevant. Basically I sent my 12.5" F6 Parks mirror to Wayne Sainty for recoating as I haven't used it for nearly 10 years and it was badly corroded.

'Wayne Sainty coated my mirror but noticed some marks so cleaned it off and coated again. Marks were still there so he didn't overcoat it. He kindly sent it back no charge despite all his work. The marks are a bit strange as they don't look like roughness. When I sent the mirror it was quite badly corroded so I assume this had affected the glass somehow. I am rebuilding my telescope so can't test it till it is finished.
Question: If the mirror needs polishing, what would be the best way to go about it? I'd like to do it myself as paying someone doesn't seem worthwhile considering a new mirror can be had for $650 these days.'

I remember it as being a very good mirror so would like to save it.

Cheers,
Mark
