Agreed. He made two observations- with a rattle can, by the time you've finished a spraying stroke, the paint at the beginning is too dry for the gloss to form when you start the next. Also, the nozzle can't deliver the amount of pigment required for a good finish.
Having heard that, I have seen some decent spray jobs done with them but the amount of work required in multiple coats and mopping would make it a labour of love.
