Harbor freight spray gun?

I ended up with orange peel in the camaro pictured above. It wasn't bad and most people would of said it looked great. But if you can prime/paint a car what is one more one step with wetsanding. Isn't to hard.

Took 1500 followed by 2000 sand paper and then buffed it out with 2 different style pads and compounds. Smooth as glass now and still need to do the last step with wax and a dual action style buffer.

I have found out it seems like single stage enamel and urethane tend to lay much smoother when its all said then done compare to a base/clear set up.
