We're a few steps closer to completing our bodywork now. All the molds are put together, and we're done with the initial sanding of two and a half of the pieces.

After all the mold pieces are milled, they are glued together. I used gorilla glue, which works pretty well, but takes a while to cure. To hold everything in place while it was curing, I used a few dabs of hot glue, making sure not to let the glue get too hot and melt the foam.

Once all the molds are put together, we slathered body filler over all of the molds. This gives a nice, strong, and sandable surface that will eventually be a lot smoother and more durable than the bare foam. Unfortunately, this is a lot of work, but we have the time right now, so we're going to go through with this process.
Bondo is based off a polyester resin, which eats foam, so we had to make our own body filler with an epoxy base. We used talc as a filler (it's cheap), mixing the two in probably 2:1 ratio (talc:epoxy), mostly by feel until the mixture was a nice, thick paste that didn't run.

After letting the epoxy cure, we have to sand everything smooth. We're still in the process of doing that, but let me tell you, it's a royal pain. This stuff doesn't sand too easily, and it's taking ~3 man hours per piece.

After we get all these pieces sanded, we will have to apply another coat of touch-up filler to fill a few small dips and depressions, and then finish the surface by sanding one last time.
