looking at refurbishing a 1990 Key West CC, has soft wood (plywood) behind the CC (especially hatch at bilge) and on starboard side of CC...wondering what to expect underneath when I start cutting out the bad deck..are there plywood stringers and flotation foam under there?? Planning on epoxying marine play back in, then paint entire inside of boat w/ epoxy paint....anybody have tips for this project?? Thanks in advance.
