Docxfire, that's a bummer. The Dent Wizards do a great job when they can get "behind" the dent. But if yours is indeed in a spot they can't get to, then I'm not sure if they have anything else in their bag of tricks that would work.
The first thing I would ask you, is what color is your car? If it's white, black, or yellow, then you don't have metallic paint and it probably wouldn't be too hard for a good body shop to fill the dent and match the paint. But any other color, and you would stand a good chance of the hood never being a perfect match.
Is the dent small enough that you can live with it, even though everytime you walk up to your car, that's the first place you eyes will look everytime.
Just remember, no matter how small the dent is, it will look 10Xs bigger to you than anybody else. Good Luck.
