It will stop rust and prevent against saltwater corrosion.

Once salt has gotten into the metal......it is too late to do anything.
You can sand blast until you think you are looking at good metal and then paint with the best stuff.......then in a couple of months it will start showing the rust again. I worked in a salt plant and nothing will protect the metal....once salt gets into the metal.
Galvanized metal last a long time in a salt environment, unless the "galvanized" coating gets chipped off.
I made some wheel fenders with galvanized metal about 6 years ago. I cleaned up the welds and where metal had been cut real good and sprayed with Cold Galvanized paint. The fenders still look just like when I installed them.
