The ceiling of the small cuddy on my Harvey dory was balsa cored and water saturated. I cut out the laminate headliner and while temps were still below zero (in Alaska) I zipped off the rotten balsa with an air chisel. Then I sanded it smooth so all that is left is like a veneer of resin impregnated balsa...and it's tough! There are some deeper spots and then there are the voids between the balsa squares that need to be filled. I intend to put a stringer down the center line with ribs from the side of the cuddy joined to it. Is there some flexible filler I can trowel on that will stick to the remaining balsa surface. My thought was to paint the ceiling with some sort of textured paint after filled and leave the stringer/rib assembly bright. I could mix epoxy with filler but hope someone could suggest an alternate that might be a little less costly. Thanks for any help!
