Use Plastic primer first then paint the trims otherwise, the paint will chip off,
Also, is the wet sanding done? make sure the painter sands the doors while they are on the car else, you'll see dhalken in the paint.I would advise you to go inside the painting booth and get every nook and cranny painted.I would also advise to get your car to be painted last in the day. as painters take the car out after half hour which results in kachra in the paint, keeping the car overnight in the booth would minimize the kachra.
