It sounds like you may have sprayed from too far a distance resulting in the paint drying before it hits the surface, and you ended up with the orange peel. Hold the can 10-12 inches away from the body. You will have to, wet sand your paint with a MicroMesh or LMG polishing kit to remove the orange peel and regain the gloss. Do any touch ups if you burn through the paint anywhere or add another coat of paint which should be a lot smoother. Add a gloss clearcoat over your paint after it has dried for a few days. If the gloss clear has any orange peel, wet sand and touch up or add another coat of clear.
