So I'm moving to NH soon and I have a 14 ft aluminum boat that is pretty beaten up. The paint is faded and scratched and is really bad on the inside. My question is I will be using it for clamming and fishing. So it will be exposed to a lot of brackish and salt water. Do I need a certain type of paint for it and I have a floor in the Boat so there will be a build up of sand and salt on the inside and Underneath the floor of the boat. Do I need paint for that too?
