Searching for #2

To paraphrase Jack Welch, you want to be #1 or #2 in your industry, so who is #2 to Simoniz in supplying cleaning materials to the car wash industry? I saw a Simoniz truck recently. The tagline printed on the truck read: "In car washes everywhere". I wonder who's #2. If there's no clear #2, this seems like an opportunity for an entrepreneur.
