    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 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.

    Good morning,
    Does anyone have a picture of the can of Rustoleum cold galvanizing compound they are using on props, shafts, etc. I see 3 different types and was wondering which to get.
    Thanks!

    This is the shiny version. The dull version says "Cold Galvanized Compound". No difference except the "bright" has a bit of glitter to it. I've used both.

    Last year I used Pettit Barnacle Barrier zinc spray on everything metal underwater. Shafts,props, rudders and tabs. Everything was clean when I pulled the boat out at the end of the season except the tabs had about 1" of growth, like I didnt even paint them. This year I'm trying the Rustoleum.

    They both are 93% zinc content. They both will perform the same. The only difference you will see is in the weight of your wallet after purchase.

    Are diving services like this cheaper if they have to do less work? I assume you pay some minimum inspection rate and then hourly for the actual cleaning work.

    I’m would not. Use that one!
    I hand been using the “cold galvanizing” for a few years. It’s awesome! My buddy bought the non “cold galvanizing” shinny one and had a lot of growth! We both used our boats exactly the same amount as we boated together every week. Just my 2cents

    How much $$ a foot does your diver charge and what do you get for that?
