Replacing Balsa Core - Few Questions

[Pburk]

Hey all,

I pretty much have all the balsa in now. It's been sloooow going between work, kids, some house projects and the occasional running out of epoxy. It's looking good and feeling pretty dang solid (I added a few more photos). Thanks again for all the help!

Initially, I was using a bunch of heavy things to weigh down the second layer. But started using screws and filling the holes with epoxy after. Probably pretty obvious but was far superior.

All that said, I am moving on to fiberglass here soon and would love thoughts on what I should order/use. Two layers of 1708? Something else? I have no experience with fiberglass and am covering a pretty large area, so something pretty simple and durable would be my goal. I might start another thread specifically about this...
