Dyno Jet with Poly Core instead of plywood?

[pegcity]

I've been doing some reading on polycore as an alternative for plywood in boat construction. It seems you can get panels preglassed so all you need to do is glass in your seams and away you go. What do you guys think about using it for a dyno jet project?

i am doing mine with pp core and cf/kevlar, better, and lighter than Al.
