That stuff sounds pretty good, Sounds like you have created an orange peel affect, This is usually caused by spraying too close, paint or primer mixture too heavy or when you spray a path on you did it too slow. Either way you should sand it back to a good smooth finish before painting or the paint will look the same, As far as the color goes lime green should cover, but may take an extra coat or two, from my experience with that color be very careful not too lay the first couple of coats on too heavy, I mean the first coat should never completely cover, Spray all the edges first then lightly coat the rest being careful not to lay too much on the edges again. You should'nt try to get a good gloss until the 3rd or 4th coat.
