    What do you guys do? I always use the Pettit prop coat my shafts and props. They always come out clean. Bottom paint rudders and trim tabs. That's how it was when I got it. I'm getting barnacles on my trim tabs every year, rudders look OK. Would it be better to Spray all these parts with prop coat?

    There is wide spread use of Rustoleum "Cold Galvanize Compound" at my yacht club. It works as good if not better than the Pettit and much cheaper. I've always had trouble with trim tab barnacles as well but this year used 4 heavy coats of the Rustoleum CGC and they came out almost totally clean. I used 4 spray cans on my 390 this spring.

    I’ve been using the Rustoleum Cold Galvanizing Compund on props, shafts, rudders and tabs. It works great!

    I’ve been meaning to try the Rustoleum stuff. Been using the Pettit stuff and seems ok in Ct,NY waters.

    I use the Rustoleum on ALL under water metal. Props, shafts, struts, rudders and trim tabs. However if a boat just sits for weeks in warm salt water the barnacles will grow on almost anything. My boat came out this year with almost zero growth but my boat never sits more than a week during the warm months. I doubt you can avoid needing a diver in Florida when then water is in the 70s,80s and 90s.

    +1 Same here, shafts, struts, rudders, props and tabs and no barnacles - still get the soft stuff when I don't regularly run the boat.

    Petit 1792 for years. SW Florida, so one of the worst areas for barnacles. My monthly diver is amazed at how clean the running gear remains, even when the boat wasn't used much in 2017 during the repower chapter.
