It shouldn’t matter, but I’d get the light bar first.
Mine was wrapped long before I installed my OEM lightbar, and I could see how a careless installer could possibly damage the wrap on the cantrails. Not likely, but possible.
BTW: If your car is wrapped, my SC has you sign a waiver for any damage that might occur during service. If yours does the same, then even more reason for lightbar first.
I have two Cyberbeasts, I did not remove the black vinyl tape I like the way it looks on both of mine, it’s an off-road light bar. You’ll understand what I mean when you try to turn it on.. kind of a pain in the ass when you have it on then you have to dim it manually.
