Bumper sticker sales can be a lucrative source of income for one who is willing to learn good selling techniques, anticipate customer needs and plan ahead.
One company sells bumper stickers kits — a few strips of adhesive paper, some magnetic letters and a couple cans of black fats-dry spray paint.
The blank bumper sticker paper is placed on a metal surface and magnetic (to keep them from slipping ) letters arranged to spell out the message. Then, the spray paint applied.
When the letters are removed, the “message” shows in the original color of the paper strips on a black (or whatever color spray paint is used) background.
