In our shops we have done eperiments with the procedures you have
outlined and did not have the success that you seen to have had. Infact
we were able to show some remarkable failures on test assemblies.

Jaques Mertens wrote much the same in an earlier thread on this
never-ending topic.

From the sound of it you are both working on big boats with large cross
sectional areas, eg solid keels, which may explain the differences. I've
only built small plywood boats I can pick up and put on top of the car,
under 50 lb. TF Jones describes using uncatalysed thickened poylester
resin for filleting on a Dobler 16 made out of polyester/fibreglass panels
substituted for the usual plywood panels. The design being discussed in
this thread is also small.
