Slarti – This thread inspired me to paint my car with a brush.
Unfortunately, all the photos seem to have been lost (Photobucket ransom?).

Where I went wrong was using a synthetic paint, rather than Rustoleum.
My paint went on very shiny, but would not sand back to a smooth and shiny finish.
If rough and ready is what you are looking for, my trials and tribulations start on this page.

Good luck, Paul.
