Why take it to bare metal? Up here in freshwater, we just clean the area for the anode. Is this a salt water thing? Or is it to prep for anti-fouling on the metal?Hello all,
Typically sand myself, but looking for different opinions / styles for bringing your prop back to bare metal.
Thanks
Greg
Been there done that. It’s an urban legend -the zinc oxide cream doesn’t last on the blades more than few hours of engine use, maybe a month on the hub/shaft where the speed through the water is lower (due to smaller diameter). It needs to be renewed frequently to be effective.zinc oxide cream (diaper rash ointment) to the entire prop. Good for several seasons.
Thanks for the info. We're heading to salt water this summer, a whole set of new stuff to learn about, like barnacles, tides, salt...I use a stainless steel wire wheel in my drill on my stainless feathering prop. It takes me 1-2 hours to get the prop smooth but I don't sweat the nooks and crannies. After a acetone or solvent wipe down I spray on 3 thin coats of Cold Galvanize. Available from Ace Hardware for $8, it is the same as Pettit's $30 prop spray. One can lasts me 2 years. I've been using this procedure for over 15 years.
I've used Desiten very successfully on the prop & shaft no barnacles at all. I do end up with vegetation. I'm also not in the water year round like many of you. This season I'm going to try the ace hardware or a rustoleum cold galvanize paint. Some say it works well, others say it's a barnacle magnet. Guess it depends on where you keep your boat.Been there done that.

tried diaper cream (forgot the brand, maybe Desiten?) and also generic ZO cream.
Shouldn't be much of an issue. The paint is basically zinc and your bronze prop has zinc in it.If I could get the cold galvanizing down here I might try it, though I worry about the dissimilar metals thing on our $4500.00 prop.
Using a zinc coating isn’t any different than using a zinc collar or hub next to the prop. The zinc should be consumed before the bronze.worry about the dissimilar metals thing
