Pettit barnacle buster vs rustoleum cold galvanizing compound

Actually the Pettit paint is called Barnacle Barrier.

A customer of mine was told that these two products are identical. Does anyone know if this information is factual?

Wow, one of the few certainties in life is the impossibility of killing a good rumor.
Both contain 90 percent zinc. Ever see a barnacle stick to zinc??? I have used rustolium here in New York /Long Island for years and never had a barnacle stick to my shafts, strainers, props or thru hulls. It's the same crap. Now, the same cannot be said for my interlux micron extra!
I’ve been using it since 2011, boat is in the water from March till oct/December I use rustolium and have never had a barnacle or white worm on my underwater gear
Where is the boat in the water? Location matters too: water temps, bio density, etc.
Long Island. I am a plank member in the silverton forums and members all around the country are getting the same results
I have used Pettit BB for years. It helps, but saying you never get barnacles at all is just not correct. I am also on Long Island. Boat is on a mooring. Prop and shaft typically will need some scraping by mid season to get the barnacles off. As had been said, location is important. Big difference between a mooring and in a slip.
I get nothing, I'm on the south shore. And I use my boat. If you don't move your boat like a lot of people , we'll only an act of God will stop barnacles
I used Propspeed the first year I bought my new-to-me boat. I'm in Long Island Sound at a slip. When the boat was hauled at the end of the season, the prop and shaft were covered in barnacles. For the price ($300 for 200ml), I expected better; a lot better. Last year, I tried cold galvanizing zinc spray paint. I think the can was $8 at the local hardware store. Not knowing any better, I put on the equivalent of a coat and a half of that stuff. At the end of the season, I was disappointed to see barnacles; not as many as with the Propspeed, but still more than I had expected. This year, I put three full coats of the zinc paint, following the directions on the can for drying and reapplying. I'm hoping that gives improved results. My friend was also painting the shaft and prop on her boat at the same time. She recommended the Petit spray paint she uses and swears by. I looked it up when I got home. 93% zinc.
Same as rustolium
Well all I can say I have had excellent results with RUSTOLIUM
Yes it’s a power boat, BTW, silverton was part of the Luhrs marine group, builders of Hunter sail boats
