I use an anti-fouling bottom paint. Probabaly the same/similar properties
as the marine paint."
Just so no one gets the wrong idea, it is not a good idea to use
"anti-fouling paint" for anything other than the bottom of a boat that
spends extended time immersed in water. Marine paint and anti-fouling paint
are two different compounds. Anti-fouling paint can have some nasty
chemicals in it and even metal oxide -- like copper -- read toxic here.
There are two major types of bottom paint: ablative and hard paints, I would
never apply either to the spreaders. There are plenty of "topsides" marine
paints available and they would be far less expensive than bottom paint.
>From Wikipedia.
"In modern times, antifouling paints are formulated with copper
<https://en.wikipedia.org/wiki/Copper> , organotin
<https://en.wikipedia.org/wiki/Organotin> compounds, or other biocides
<https://en.wikipedia.org/wiki/Biocide> -special chemicals which impede
growth of barnacles, algae, and marine organisms.
"Hard" bottom paints, or "nonsloughing" bottom paints, are made in several
types. "Contact leaching" paints "create a porous film on the surface.
Biocides are held in the pores, and released slowly."

[4] Hard bottom paints also include Teflon and silicone coatings, which are
too slippery for growth to stick. SealCoat systems, which must be
professionally applied, dry with small fibers sticking out from the coating
surface. These small fibers move in the water, preventing bottom growth from
adhering.
