Hi, I've been thinking of doing this and presto!
The kelsal method is usually just one side of the hull. Any reason for not doing vertical joins? How uniform did the aerocell bend when heated? Infusion can be done within female moulds it's just a way of getting the resin uniformly over the cloth and being able to lay up cloth in a dry state. It also reduces the wet lay-up time and vacuum bagging to one step. It should create a much stronger bond between the glass and resin and the foam.
