well, my dad has a 98 cajun bass boat with a painted steel trailer that has never been dunked in salt water and it still has original springs. i have a 97 al trailer that is on it's second set of galv torsion axles. i know guys that carry a pump up garden sprayer and go around and rinse after launching and they say they can tell the difference. don't know if we haver a higher salinity, but this stuff is unreal. i have to put a new set of leaf springs on the scallop boat every 2 years. but it is 35 miles from here to st joe, so it dosen't get a bath for about an hour after dunking.
