As posted on here some time ago, my wife and I applied Coppercoat to Capricious in the late spring of 2014. Since launching later in 2014, Capricious has been constantly in the water until yesterday, when she was hauled out for cleaning, polishing and some gel-coat repairs. We have occasionally used a soft brush to clean the waterline and somewhat below. Capricious was sailed from the Clyde to Titchmarsh on the East Coast in the spring of 2016, so she has been in both the clear waters of the Clyde and the muddy water of the East Coast.

The pictures here were taken immediately after she was hauled out, before pressure washing. I am very pleased with the result! The slime and slight growth you can see was removed very easily by pressure washing. There is some growth of banrnacles and tube-worms on the keel, but nothing substantial.

Where I am in Croatia it's those damn tube worm things that leave a white cast which are the only problem as everything else comes off with the pressure wash. They are a devil to scrub off the Coppercoat as well. :(

I've successfully used Starbrite Boat Bottom Cleaner in the past to dissolve tube worm cast and barnacles from props and keels:-

Fortunately, they came off with the boatyards pressure washer - a more powerful one than the domestic types.
 
Looks pretty good Paul. I had mine done professionally in Jan 2015 and it looks very clean. They advised against CC on the keel as they thought it wouldn't last. So this year a quick whizz off the rust, prime and AF - not too arduous.

I'm out for standing rigging (19 years). Next lift summer scrub 2019.

I think there are a few rust patches on the keel - but it is mostly still hanging on there. It's far better than I feared - I know how bad the casting was when it was grit blasted! Not sure why there's the accumulation of barnacles etc. at the bottom of the keel; there's plenty of water below her, even at the bottom of the tide at Titchmarch. Presumably it just pokes down into a different ecological setup.
 
We've just finished painting ours and hope it comes out as nicely as yours in a few years! The Med might be more of a harsh test for it though...

I have more barnacles on my prop and shaft than I have ever seen.
