A little progress... I've shaped a single fuselage out of modeling clay and shot it next to a mirror to simulate its counterpart.
Issues:
1) What to do next. Possibility #1 is to make a mould out of plaster of each fuselage half, then cast a copy to use as a shape for vacuum forming. Possibility #2 is to take that same plaster mould and lay fiberglass cloth and resin on the inside of it. At any rate, I figure great female moulds will be key to making this thing symmetrical.
2) I think I'll graft the headlight (including long horizontal strake) and tail light areas from the 2 kits I bought instead of trying to shape them out of clay.
3) I have to find out a way of working the rear fender arrow motifs into the car too. Also the rise just aft of the B-pillar. No solution yet, but for the long horizontal chrome trim on the rear fenders, I'm thinking of making that just a groove, maybe to intake air. I dunno.
4) It looks too "race-car" still. Maybe changing the shape of the cockpit surround. Again, I dunno.
Lost and searching, as usual...
