The "negatives" can be used to store the completed wing perfectly. The foam is used to take small shearloads and support the primary structural element in absorbing tension and compression loads. Some ultralights have a foam rib core with an aluminum cap strip bonded to the edges to do this. How To Make Plugs For MoldsDifferently. I used a gravity fed system, which pulls the wire through the wider chord of the wing slightly faster than at the tip. One advantage of making foam wings is that it's easy to be both fast and precise. 4 years ago I used a special purpose Hi-Temp mold release wax, but there are other alternatives that are easier to find.
