We basically use this process, but we use a different Rustoleum product and it works fine.
Don't forget to take into account the width of the laser beam when laying out your traces. Don't layout any traces less than 16mil, because you'll only have 6-8mil left after lazing. Also, spray on only enough paint to cover the board, otherwise that's more airborne, burnt paint that will land and fuse back on the board.
