Re: Cored deck soft spot repair
When I was doing the recore on my decks, I did a lot of research into the best core material and decided that traditional balsa was still the best material to use. As Tom has mentioned above, the common problem with balsa core is that it was never properly saturated to isolate the individual blocks. That is totally avoidable if it's done properly. I would be very hesitant to do all that work and then trust in the long-term adhesion of epoxy or polyester resin to a plastic honeycomb surface. Once balsa is sealed and saturated it forms an extremely solid surface on which to apply the fg.
Also, remember you need a 12:1 (or close to it) ratio on bevels, easily done with a grinder with a 60 grit sandpaper disk. Lay in the largest piece of glass first. West System has a good how-to page on this.
