Good evening Trawler friends!
Any advice for this product? Just saw this at West Marine and I’m wondering if it’s worth it. I run about 7 Knots and 120 hours per year on my single engine Mainship in the Middle Chesapeake Bay. Thoughts?

Thank you for the response. Man... that can of spray paint is not cheap.
Also good to spiff up chains and anchorsYou can get the same "Cold ZINC Spray by Rustoleum at lowes/home depot for $7.99. It does work but only for about 18 months in my experience. Doubt it would last on hi speed props but on Trawlers and their 2:1 and 3: 1 at 1800rpm---------OK
"Galvafroid" comes in brushable liquid form as well as spray. Usually cheaper, and you could load more on. Their website doesn`t mention antifouling use,but it seems a similar product.

Barnacle Barrier has worked well for us in the Chesapeake. In fact, we just had a diver go below in Charleston before our return trip, and he told me props and running gear are absolutely clean.
Rustoleum makes a similar cold galvanizing spray-on product that folks have said is virtually the same stuff (from their reading of the MSDS)... for something like $5/can. Haven't tried that.

Does electric shock kill barnacles?
So, high rpm has no effect regarding reduced durability on prop blades??
It works for me in the Northwest. Boat hauled today, after a year and the only growth on prop, was on the nuts, which had a carpet of barnacles.

I've tried this, the cheaper Rustoleum spray on zinc , and also Propspeed.
I believe the Rustoleum product is the same as the Barnacle Barrier. One way to get better protection is to use the zinc spray (either product) then use Petit ECO anti-foulant paint on top of the zinc spray. The ECO is water-based and also zinc based so you are not adding a copper product over a zinc product. I used that (total of four layers of spray and ECO). Quite pleased with the results after one season in the Chesapeake Bay. Since I haul every year, can not speak to extended periods of time. I suspect I have not reached the life of application on many areas because there is generally lots of ECO on the metal when I haul.
For re-application, if there is still ECO, I just coat with more ECO. If the gray spray is visible, I sand down the area and re-apply spray. BTW, I use white ECO cause it is easy to see underwater.
