Are there any issues with painting parts and panels a week apart from the main body of the car?
I have several parts that need to be painted off the car, like trunk lid,fender extensions,ect.
I don't have the room or time to spray everything in one day.
Using cc/bc

It's done all the time but takes a little extra effort to make sure everything is done exactly the same. Gun settings, paint mixing, primer color, distance from the panel, overlap, speed, number of coats, etc.

Another help is to have the panels sitting in their installed positions while spraying. (i.e. doors vertical, hood and trunk lid horizontal)
