My friend bought the material and paid his neighbors high school kid $500 to wrap his car. It was in primer and he wanted it to look good for an event. Was it a pro level job-no. Did it look great- yes. A whole lot better than a mat grey blob. I think the decals break up the panels and take your eyes away from parts that might show ripples or runs in the primer.
Like anything, proper prep is 95% of the job.
