balsa core material

[flyingfrizzle]

Found a deal on a bundle (17 2x4) sheets of of 3/4 end grain balsa core material. Wouldn't go out and buy this normally but got it cheep enough it was hard to pass on. I got a few ideas where to use it but got to thinking about how it was used every where on the seacrafts originally and was thinking about re-coring the floor in my 23 with it. Was planning on using the fir marine ply but now that I got this why not. Well I was hoping some of yall guys could tell me if it would be fine or why not. My main concern is how long it would last vs the fir. I plan on glassing both sides fully not just resin coating it.
