I think the idea of a fuel door with a lock for the contour is a great idea. I just have one problem. I don't like being told that I am incompetent and that my ideas look like crap.
I don't know who taught you how to sell but whoever they are they probably couldn't sell an ice powered heater to an eskimo in the middle of winter.
Do you really think anyone would be interested in a product where they hire a person to basicly come and tell the customer that their ideas SUCK, and to buy their's.
In fact I would have to say that the only thing that looks like crap to me would have to be your fuel door (especially the Cobra emblemed one).
Your idea is a good one, but your sales pitch needs a hell of alot of work.
Just my opinion!!
