the trailer under the larger boat in my sig needs some work, its painted steel and welded solid, its a good trailer but it needs to be sandblasted and painted soon or i fear it will be too late to save. i launch 99% in salt water- am i wasting my time trying to save a non galvanized trailer? the other question is after renting moorage and doing the work on the trailer would i be better off just buying a new(er) one? i havent priced anything yet so i dont know what i could expect to pay. thanks
