b19: Resin is poured onto the inside of the tank panel which was dry-fitted to
ensure it will go on without trouble.
|
b20: The epoxy is squeegeed out. It seals the inside surface, adds strength to
the curved tank, and prevents resin starved joints in the tank-deckbeam fillets.
|
b26: The tank beams are first coated with unthickened resin.
|
Jb13: The tank beams receive a layer of epoxy thickened with microballoons and colloidal
silica. The thickened resin serves two purposes when the tank panel is stapled down: the bulk of
the thickened resin oozes out to form a fillet and any remaining resin bridges small gaps.
