James drilled the attach holes clear of excess resin, then I filed down the flange extension to final size. After that James held the torch while I treated all the internal tank seams with ProSeal ... what a fun job :-) The final task was to fill some minor depressions in the underside of the flange with resin & Aerosil, layer with peel-ply and to cleco the tip back in the wing while it sets.
