Understand that anytime you spray paint you are shooting round droplets of paint through the air, they land on whatever you are painting and under ideal conditions, flow together and make a smooth as glass finish when the droplets dry enough to stop flowing. I control this process using the correct catalyst and if used, reducer for the temperature I am shooting the paint. This is a dance between the elements you have no control over outside of a professional paint booth, and the catalysts you are using. The containers usually have a range of temperatures to use at like 60-75 75-90 etc.
Dries too fast, you get orange peel, or worse, too slow, you get runs. I have been painting cars since the 70s and have a good idea what the brand of paint I use will do and adjust accordingly. Be advised, you can do EVERYTHING correctly and still have a poor outcome, humidity can change, compressor quits. Back in the 1970s I painted a brand x 52 hardtop a beautiful two-toned root beer and cream, Looked stunning, closed the garage doors leaving a gap for the fumes to move out and went into the house. Came back 45 minutes later to look at it and a cat had come into the garage, walked across the trunk lid, top and hood. Got to start over and lost money on that job. Some lessons you learn the hard way. I had the good luck to have professional friends mentor me over the years. Using spray cans is a gamble at best. At least get spray cans that put out a fan shape spray pattern instead of a round circle of paint. Actually, All painting is a gamble between what you can and cannot control, you just try to have the odds in your favor.
