Vinyl paint? (exterior)

I just learned about vinyl paint and am considering using that on the front skirt (not sure what you call that) on my Ford F250 truck. It's a dark gray color and isn't looking so good these days. If you prep it well does it actually look pretty good? I don't want it to look painted. There's a place here that blends auto paint and they said they can do vinyl paint as well. Is that the best way to go? How do you get the closest possible match to the original color?

Thanks so much...
