If i was you dude, id be trying to get that body kit painted asap, i wouldnt be too keen on having just fibreglass hanigng off my car incase it cracks, chips, etc. Paint will help to protect it. But thats just me.
If/When you do respray it, get used to seeing your car like this.... for a long time........
Unless of course your just gonna spray the outside, and not worry about the engine bay, etc.
