well, if you are pretty sure that you thoroughly/properly prepped the surface, i think it would look decent after you wet sand the paint and clearcoat it. After wetsanding, don't worry if the paint surface doesn't look shiny or glossy. just make sure you clean the surface completely and clearcoat over it. After all, if you've already painted it, you might as well finish it and see how it looks.
You can get clear spray at local auto shops. I bought some at Kragen and I'm pretty sure Pepboys have it too. hope this helps.
