I have 12ft 91 sears game fisher I bought. Just wondering if could just re buck the rivets and fill the seems with 5200? Also i use this boat in puget sound for crabbing, so would it be ok with saltwater exposure? I cant really afford steelflex. Any ideas as to what types of sealents and/or epoxies that are relativly resonably priced to use or just ideas would be appreciated!
