Very impressive.
I have future, but no airbrush. So I can only use it to shine up little parts. Aparently you can use on bodies if you apply it with a brush **shudder** as it is highly self levelling, but the thought of it still creeps me out. I may try it on a test body I have lying around... In the meantime, I'll just spray Tamiya Clearcoat...
Why couldn't you wetsand it? I highly doubt it's water soluble after drying, considering it would be used on household floors...
