Anti-Fouling Bottom Paint

[crazycarl]

After over a year sitting in brachish water, I pulled the boat to clean the bottom. I noticed the only places that needed cleaning were the waterline, and the bottom of the keel where the anti-fouling paint has worn off from "beaching" the boat many times. While being layed up for 4 weeks and not able to get to the boat, the new rudder dropped and you can see what only a month's growth looks like. McGyver painted the bottom maybe 10 years ago with a hard anti-fouling. It has lasted all these years and has performed admirable. The boat has been in brackish water for over a year with very little growth. My other boats need cleaning every 4 months. Mac, if you're reading this, I hope you can remember what you used.

I am pretty sure yours was Fiberglass Bottomkote by Azko Noble Company product line named Interlux.
Should be a color Black in that line.
I think now it may be called or reformulated into Fiberglass Bottomkote NT.
Thinking about things I doubt I would have used a Petit product, and I would not have suggested Micron CSC which is a ablative, as trailering it would rub it off or shed itself too easily....
Very happy to see a job hold up, getting ready to do mine sometime as she is finally ready for a refresh!

FWIW, the boatyard that had a direct tap into my bank account while I went through a Chrysler 20, Mirage 236, Bayfied 29, and Freedom 33, and my own experience, holds that Petit is the bottom paint of choice in tropical salt water (Pensacola in my case) and that the effectiveness of the colors in descending order is red, black, blue, and green.  I understand that Interlux does a good job in cooler climes.
