I've got two gallons of Blue Water Copper Shield 45 ready to go on this
Spring.

Hmm. I note that unlike their Copper Pro SCX 67, the marketing blurb for
this line doesn't say "can re-launch after extended haul-out while retaining
original antifouling properties."

Sure you ordered the right stuff?

Yes, the current version of Copper Shield 45 is rated as "Multi-Season"
but Practical Sailor does not have it in the 18 month survey so I'm not
sure if it will go two seasons.

However, I've never had an issue with extended periods with any ablative
as long as the boat keeps moving. I only had a problem last fall after
being idle for 7 weeks. My query was not about paints, but whether
other people noticed abnormal growth at the end of last season.

Yes, it seemed to be a very active season for bottom growth. Having
barnacles is still a paint failure in my book. As long as there is
Micron Extra covering a surface, there will never be any barnacles.

With the amount of effort involved in bottom painting and interim
cleaning, the price differential between paints is of no consequence.
If Micron Extra was $300 a gallon and "something else" was $100, I'd
still advise Micron Extra as the better deal.
