Gasket, seal, skim or bin?

Trigger:
I would start again, without any localised rubbing.

Thanks folks.

@Ka-ja...The wet and dry was stuck down well with double sided tape. I was so surprised it held but it worked perfectly.

The general consensus from this and other forums is that it should be fine - the gasket seals on the steel liners and that some gasket sealant should sort the low spot. I've been recommended Hylomar blue.

NOT HYLOMAR if any gets in an oil jet it blocks it

Completely agree, I remember finding this and writing it up in my work book as an apprentice when my head fitter said well done for spotting it.
I was always told 'figure 8' pattern though, we'd get something thrown at us for circling while lapping bronze pistons slippers for hydraulic pumps.

Sorry OP, not much of use for you in my reply!
I would move away from paper if you have paste.
The glass is just a flat lapping block, just much cheaper than an industrial one, it is tough enough to take paste as long as you keep using as much of the surface as you can, try figure 8's
