I'm trying to select an ablative bottom paint that won't break the bank and will keep the slime off of my boat. In the past, we've used West Marine's CPP. It's a good ablative paint, but a brown scum line usually develops within a month of launch. I'd like to give West Marine's Pure Oceans ablative a chance because of it's "greener" qualities, but I'm concerned it will not last as long as the CPP. I know both of these paints are not listed as "anti-slime," but have any of you been able to compare their effectiveness? I'm also thinking of the PCA Gold paint with biocide. Any thoughts? Thanks.
