He does great work, but does not give you the words on a curved line that matches the arc of the spoiler itself... what you get is straight as an arrow.
What I did was to cut a slit through the backing paper from the top down to a quarter of an inch of the bottom between each letter. Then I taped the floppy thing to my spoiler to get it just right and removed the backing one letter at a time to get it down right.
