hello to all this is my first post with my first boat restoration i have been following iboats for a while.. the boat is a 1983 sea ray 245 cruiser. I had some rot spots in the ceiling of the cabin that i cut out where the horn wires went through the deck and water was coming in. The core is balsa wood can i use plywood to patch this or do i need to use balsa wood? or any info on what to do next would help out and be appreciated. thanks in advance.
