grinding paste and some furious lapping should sort that out

as long as both surfaces can be made to go a uniform flat grey colour you are sorted

the one on my race car was a LOT worse than that last time it came off!!!

It certainly doesn't look great. However, all is not lost.

It looks like you have a couple of serious high spots. Get these removed first, using a die grinder or similar "Dremmel" type tool. Once these serious high spots are clear, lap the flywheel onto the crank using first coarse grinding paste then fine grinding paste & if you are feeling particularly conscientious then with Brasso (I never bother with this last stage.

As long as there aren't any serious high spots left & the VAST majority of the remaining surface has taken some "grind" you should be OK.

The mistake you made was buying a second hand flywheel. People only sell them when they think they are knackered.
