Seatback aft face had a couple of lean areas, not a significant amount.
Finish IP foam and join together with 5 minute epoxy, no flox. Still exothermed pretty quickly and had to make another batch. Used 45 x 90mm timber as prop for hinge joints, something thinner would have worked better.
Cut out some glass, stopped by impressive thunderstorm causing roof leaks.
