I'm rebuilding the Thermoquad from my '72 Duster 340, and the the air horn casting in the primary fuel well (not sure what to call this) seems to be in rough shape on both sides. Do y'all think this will seal? I hit it really lightly with a sanding block just to bring up the highlights so that the unevenness is easier to see in the pics. Shiny = flat, dark = sunken.
