If tanks are sealed, very little is needed. Maybe the small quantity Vans sells. I used it for the control surface stiffeners and NACA ducts. Used Fire Barrier 2000+ for the firewall.
My tanks used a little over a quart so I had plenty for odd jobs. Fixed holes in my Thermorest camping mattresses and a few other things.
