I posed somewhat of the same question on the other forum:

“So here is a follow on question – if using an antifouling paint like Micron Extra, do you need to prime/seal the hull first to prevent blistering, or will the Micron do that as well, even though it will eventually wear off and need repainting (Micron says you can put it directly on a bare/dewaxed hull)?”

So I emailed Micron and they emailed me back and said that the 2 coats of Extra on a bare hull will not guarantee against blistering and recommended sealing/priming it first. This was the same suggestion from the dealer this year – although they just repainted the bottom last year (and there was a lot more wear than this year – i.e. you could see bare hull after the power wash - ??????). I was a bit confused (and upset quite frankly) so they put some heavy coats on this year and I will address it when I pull the boat…
