Piston coating:
I dropped the two pistons that had damaged coating off to the engine coating specialist today, for refurbishment of the anti-friction coating. The two guys there said; "No problems at all, we are doing a batch of pistons this Friday.. $40 +GST per piston" for the entire process: (surface prep and application)

Looking forward to getting them back.
I'm saving about $400 doing it this way, compared with buying two new ones.
Cheers,
