For so many reasons - legal and just sheer competition are the main ones - we don't talk about what we have in the pipe line. Few people realize that we take the International Valve Cap Oath seriously: "First, do no harm". That means testing in initial small groups to get a reaction to our unique marketing program, internally called Valve Caps Might B U. Testing goes on and on until we get the right product and we put it out in the real world.
Relative to your inquiry about a "Green" cap, I am at liberty to say that we are getting a very good reaction from one of our prize target groups: young computer site wannabes who pretent they own expensive cars and have them all slammed and rock'n. This group likes the idea of a "green" valve cap, but our initial analysis indicates that it is not a matter of fuel economy or a need to be environmentally concerned. It looks as if the groups we have been examining just happen to like the color green and anything associated with it. It is in that light that I wouldn't be surprised if, by next St. Patrick's Day, you see us offering a "green" valve cap with green neon lights. It could be a big, big winner for us and it will help people identify VALVES R US as a domestic company committed to the green cause.
