Try colorthane from (Schirwin williams industrial) it has to be the finest 2 part paint I have ever shot. Cost is about $190 a gallon including the hardner but you won't be using the whole gallon. this stuff is so damn hard its hard to wet sand. You can shoot a clear coat if you want but it shines really nice without one. wet sand it and polish it up. amazing stuff! and its really hard. use a good charcoal respirator the isosianates will get you if your not carefull with it. Charcoal, Charcoal, Charcoal.
Hope this helps
