Lungs weren't made to filter out latex aerosols, organic solvents, urethane, epoxy fumes.
Any time you're spray painting, you should at least have a dust filter. Coughing up paint may be something you put up with in an unregulated factory, but given that masks that do the job aren't really that expensive anymore, your lung capacity will be a lot better when you're 60 and need the reserve you burnt off in youthful immortality.
Some of the paints out there can confer permanent, life-threatening allergy. We had a whole paint shop workforce here that took pride in skirting safety. Until a good portion found that painting is no longer a career option. The shop owner got religion after that.
Paint sprayers have a pretty low PSI requirement. I'd be more concerned about the CFM (Cubic feet per minute) rating of your compressor. That would indicate whether it can compress the air fast enough to keep up with the sprayer.
Unfortunately, there is only one way to fix your boo-boo. Sand it back down to metal or enough to remove the drips. Next time, when using spray paint, remember several very thin coats are much better than one heavy coat. Always start the spray away from the object you want to paint. Move smoothly and fairly quickly across the area, then go past the end of the work before stopping the spray. Let the paint dry a bit before the next coat. Be patient, smooth and quick. Trying to put on too much at one time caused your drips. Good luck.
