The PO kept my boat in fresh water for the last 20 years, so it had no zincs attached to the strut. I now keep it in the south Puget Sound.
At last haul out, the yard guy commented that I should at least, 1) not paint my strut with copper-based anti-fouling paint (as I had) because it can cause the bronze to be sacrificed vis-a-vis the copper, and/or, 2) scrape the coatings off the strut and attach a strut zinc.
Under the anti-fouling paint, the strut is covered with a thick (many times thicker than paint) whitish coating. Where still in place, the coating adheres very well and is hard to remove. The white coating has, however, chipped off on maybe 10-15% of the surface of the strut.
As per the yard guy's recommendations, I'm planning on:
- Brushing the strut down to bare bronze (the bronze appears to be in good condition on the half I have completed)
- Attaching two small disc-zincs (one above the other) to the trailing edge of the strut (the trailing edge is flatter than the leading edge).
- Painting the strut (after the zincs are attached) with this stuff (leaving the zincs unpainted)
Is that a sound plan, or should I have sought input here BEFORE sanding down half of my strut?????
