Craig,
The lower parts of the Amphicar were put together with stitch welds.
These welds do an inch here and there, not letting the heat build up
and distort the metal. Then you go back and fill in between the
previous welds, gradually filling in the spaces. The upper joints
where the body panel come together were welded and then lead was used
to flatten the areas across the joints. The welds should ideally be
water tight when you're done you should coat the interior with
something that will take care of any pin holes you might have missed.
I used Dupont's Corlar 25P coating. It is designed for continuous
immersion under gas and oil. It requires no primer, is not UV
sensitive and is available in whatever color you want for your
interior. It dries flat and, when rolled after application, looks
almost exactly like the original coating that Amphicar used. It's a
thick, two part epoxy that will take care of any leaks. It's perfect
for Amphicar interiors. Amphicar used such a coating up to the
steering box. In front of the box and inside the trunk I simply used
a high quality marine deck paint with the maximum amount of flattening
agent in it so the irregular surfaces inside don't show.
