Question... does anyone know of a Canadian (Ontario specific) supplier of cardboard products such as the 6mm cardboard in this build??
The best place to look at is your largest box store manufacturer. The place I went to makes boxes for other companies. When I asked to buy the sheets, they were confused as to why someone would want 'clean' sheets without it being folded already. Anyway, I think obtaining the sheets are not nearly as much a challenge as getting it home! I used the same flatbed trailer as in the beginning of the thread to get the sheets home. But remember the sheets are 2.5m x 2.4m (about 8 feet by 8 feet), which is quite large! I had to take two large blankets along to cover the sheets, and then tie them down with ropes, because if I drove home and one of the sheets caught the wind, it would have ripped the cardboard to shreds (without the fiberglass the cardboard is still quite flimsy.
Here is a quick pic that I got off the Internet to show the differences between double wall and single wall cardboard.
Double wall (below)
Single wall (below)
Remember, you preferably want double wall. It is quite a bit stronger than single wall (and will keep the walls straighter).

First, thanks for your blow by blow pics and explaination of the materials you used. The reason I mulled around foam was strictly for winter insulation. Now (in light of what others have mentioned about "expensive" foams), I'm thinking cardboard for the forming. Then cheap Home Depot sandwhiched on after resin curing.
Second....
(And of course, if your name is Sep Blatter from Fifa (soccer), you'll say "Soes Efrieka")
You lost me on that one, but a good Alabama pronunciation would be "South Africker".
Woodstramp,
Your idea will work. No problem. But go and find out about the 'expensive' foams too. Here in South Africa the price difference between polystyrene and polyurethane is not nearly as much as one might think. Go to places that manufacture industrial cold rooms and refrigerators. They all use polyurethane sheets to insulate the cold rooms, because it is far superior to polystyrene.
Another option that might work (but try a test piece first) is to buy a roll of ordinary paper (brown paper or any other type of paper), and paste it to the foam. If you have patience you could also buy masking tape (the paper based type - not the plastics) and mask the entire tear, made out of foam, and then fiberglass it. The masking tape will act as a barrier between the resin and the foam, and you'll have an incredibly strong bond. But as I said, make a test piece first!
And o yes, the soccer world cup was in South Africa recently, so we heard Sepp Blatter on the news almost every night. He is the head of FIFA, and is a French first language speaker. If you are curious as to how he pronounces "South Africa", look at this short clip.

I don't know whether I should laugh or cry!
how much sand paper did you use
