It would actually work pretty good to make a kammback for a car.
You could pour into a cardboard mock up , so you get it basically right in the first pour.

Foam-wrapping instead of bubble-wrapping!

Wicked. Nice find. It started out shaky, but had a nice finish.  |

Well, they claim the first thing to go is the mind, but I can't recall what was second...or third...or fourth...

I've see that Russian guy thing before, pretty amazing what determination can do with little resources.
The issue facing many of the weight sensitive home built hovercraft builders is the foam will absorb moisture right out of the air/atmosphere.
You don't even need a pin hole leak, leave it out in the rain, or floating in the water for the weight gain due to air moisture content to show up.
Maybe a car can deal with this weight gain better than a hovercraft.
I do like that the foam is an energy absorber in case of accident though.

Quoting myself from this thread:
Quote:
Consider plywood for the ribs and cedar for the skin. A friend of my[sic] built a egg-shaped house on a Ford flatbed truck back in the 70s. He made plywood ribs, ran light wood stringers and shingled the whole thing. When it was done he had it sprayed out inside with polyurethane foam. What was a wobbly structure turned into a solid block of foam with the shingles embedded in the outer surface.
Where he shingled it vertically like a stationary house, you could turn the shingles 90° so they lay like fish scales.
|
Edit: He laborously hand tapered each shingle to fit. If I was suggesting it today (as I had then), I'd go for beveling each shingle[s thick edge], hot-melt gluing each one and using a geometry more like this:
Frameless!
