I used Micron CF last year. I'm on the Patapsco so the salinity ranges from 10-20 ppt. I had some leftover Micron CSC, so I put that on the keel and rudder and CF on the rest of the bottom. Couldn't tell the difference in terms of performance. CF isn't copper, so I'll put it on the prop shaft this year. Painted that with zinc last year and it turned into a barnacle farm. I used the Petit stuff for my knotmeter last year. Did not work at all.. Gonna try really thick grease this year - on the prop, too. It became a barnacle farm last year as well. Couldn't make but 4 knots 'cause the prop was so fouled.
Slime is always an issue around me - all boats.get slimy. Wiped it off twice last season, once by myself, once by paying a diver. Diver said it was not bad. Very few barnacles attached to the hull, except for the prop, shaft, and knotmeter. I think the CF actually worked better than the CSC for barnacles. Dan SheerPegathy LF38Rock Creek off the Patapsco
