You haven't provided the most accurate description of the paint, but I'm guessing you have what is known as Orange Peel.
The orange peel effect is caused by premature evaporation of thinner,
incorrect spray gun setup (ie. low air pressure or incorrect nozzle),
spraying at an angle other than perpendicularly, or applying excessive
No matter how smooth the paint may have been applied, the texture forms as the paint is curing. You haven't explained if this issue is in the base color coat or in the clear coat finish. This can sometimes be fixed via polishing, but often requires that the area be repainted..
And by the way... don't discount a rolled on paint job. Here's the link to the $50 paint job, where the guy paints the car with solid enamel color in his driveway using just a paint roller. No spray guns involved. No safety mask, no paint booth. Easy, reliable, relatively safe, durable.
