Do the jambs etc first then get the car ready to spray if it is hot you won’t have time to get around the car without over spray just paint the outside by itself if you don’t have a booth you will be working to get around it before it is dry pay attention to the mask you are using a real mask...
The sata mini is wonderful I use one hardly any orange peal devilbus has some guns that re pro and not too much money the cheep guns are harder to clean not finished as nice inside probably ok for what you said
