Wouldn’t it still have to be pressured for humans?
If an astronaut could step out of a shower, say, that applied a compound of some sort to his skin, then into a radiation chamber that activated the compound and turned it into a skintight constricting spacesuit, we'd be well on our way to Buck Rogersville! And we'd owe the idea to an insect.
Putting on the spray and irradiate suit would also be a LOT easier than getting into the space suit depicted in YouTube video, which I understand is a real bear.
