Although I was told by someone on their stand at last SIBS that a light abrasion prior to first immersion helps to activate the new coating.
I have just finished abrading the hull prior to re-coating later this Spring and yes it is a b***** awful job. On the other hand, so is scraping off old antifoul.
I experimented last winter by abrading a patch of (15 year old) Coppercoat and at mid season scrub the patch was clearly defined and noticeably less slimey than the surrounding area. I wasn't present for end of season lift out.
