Yup! Orange peel is orange peel, caused by excessive moisture in his air lines. There is a product you add to the paint to prevent orange peel, he was too darn cheap to add it,, and probably didn't want to take the time to service his moisture trap, or didn't spend the money to install one!
I would nicely inform him you are dissatisfied with his service, and if he does not make it right, he should expect a visit from the local BBB...
