Bottom paint - Canada
Posted: Fri Jan 13, 2023 12:04 pm
Hi all,
Looking to get some protection on the bottom of our new rig. Based on the great information on previous posts, including full schooling from Chaps, I'm leaning towards ~4 coats of epoxy barrier coat (InterProtect 2000E), and 2-3 coats of antifouling.
The problem/question I have is that Tri-Lux II has been discontinued in Canada and I don't believe there is another copper thiocyanate based alternative. I've been told that Interlux recommends a Copper Oxide (ie. Bottomkote) over 4-6 layers of epoxy barrier coat, while keeping the barrier coat a few inches above the leading edge of the anti-fouling at the waterline.
I'm concerned that a scratch in the bottom paint (eg. from beaching) will result in exposing the bare aluminum to harmful copper. Does this seem risky, or am I overthinking it? Does more epoxy barrier coat provide better isolation, and mitigate this problem?
Many thanks,
Mike
