I have an invention, well more like an idea. What can i do?

Question

I thought of a good idea to put on an already made invention, on the car-if you must know. what can i do to make people hear my idea?

Answer 1

Ummm, Are you trying to make money here or just do some car improvement?  

Hire a PR person to spread the word but first copy right the idea or get a paten or someone will certainly steal the idea if it is a good one and run with it.

Answer 2

Require anyone you discuss it with to sign a nondisclosure agreement, until you figure out if its a viable idea.  That way you dont have to go to the expense of a patent yet.
