Re: Using Bottom Paint on Brass Propeller

I've been using the Petit Zinc Barnacle Barrier spray paint on my bronze 2 blade prop (a $20 can will last you a number of years). It is not the best protection like MaxProp but works ok; still need to clean barnacles off prop mid-season.
At least with a zinc spray coating the zinc in the bronze seems to be protected from electrolysis.
de-zincafication is a real word and is what MaineSail's photos show.
YMMV
