Makes perfect sense. My Smaragd was Kevlar with a 1/16 layer of white bead foam with 3/4 oz.?? glass cloth over it. It was very fragile. IMO. I think part of that was using Kevlar. While Kevlar is very tough it seems epoxy does not really seem bond to it. The epoxy just seems to encapsulate it.
Thank you for posting your build and putting up with all my questions. I'm learning a lot!!
