Galvanizing will give you the best protection, especially if the trailer is
going to be used in salt water. I even galvanize trailers or any other
steel fabrications that are just going to be used around SW.
The galvanizing tanks are @ 800 deg. F so your axles could not be dipped
unless they are disassembled. Also holes must be drilled into closed tubes
so that the zinc can get into and out of the tube and also to avoid an
explosion in the hot tank. Call the galvanizer for all of the rules that
have to be met before taking the trailer to the plant. It's not necessary
to sand blast new metal but I do blast all of the welds just to insure that
all of the flux is removed.
I would not even consider painting a trailer that was going to be used in
salt water!!!

I would take the frame somewhere where they could 'hot dip galvanize'
it.
They can't do the leaf springs. believe the hot temperature affects
spring
steel.


Also an option.

We have torsion-bar axels, so no springs.

Though I don't know how hot the galvinizing
process is and I don't know what temperatures
the rubber in the torsion axels can stand.
