Spray paint to paint rear panel?

[SplitFire414]

In an eariler post on camaroz28.com I said I was going to be putting a neon behind the "camaro" panel. Well when I went to pick up the panel, they told me wrong over the phone. They only had firebird pieces and no camaro's. Well, I found a place that has a blue one and I was wondering how well bumper spray paint (flexible) would work. It's flat black, so with a clear coat, would it shine?
