Here is the start of our car, an XO/GL, think bellytank but more swoopy. I say our because my brother (sentinelT) and Tom (6inarow) are on board so far. What you see is the developement of the nose of the car. A foam buck getting shaped to pull a mold off of. laminated blue house insulation. Glued with whatever silicon caulk I had to use up from the house project. Basic shaping, electric chainsaw, Japanese pullsaw, cheesegrater. More shape Pullsaw, refining the shape, ready to add more foam Above, first coat of mud, Evercoat Rage. Didnt hurt foam, but too pricey. went to drywall mud to rough it out, below.
