Question; if I leave it on how fast will it corrode the steel? It is ablative paint. Do I risk it? Once the boat is in the water it will have light use for months, until restoration is complete.
Most bottom paints in use where I have my boat have a high copper content.
Everyone I know paints their rudders with it, and most have SS rudders. I certainly do. I haven't noticed any deterioration of my rudders in 22 years, so whatever effect it has is negligible.
I also paint my props with the same paint frequently. For a few years I was leaving one blade unpainted, just to see if it made any difference. It does, as unprotected, the barnacles are bigger and more densely attached. Those prop barnacles will effect performance more than any other factor, so paint those props. I haven't seen any deterioration in the bronze props either.
