so you trim and let some paint show..?
yeah. its the same on cargo vans. on the vans (ford) there is usually a lip kinda thing that creates a nice line to cut on. i have no problems letting paint show through if the trimming is done correctly and uniformally.
we have to remember that unless specifically specified and PAID for, these wraps are advertisments, not paint jobs. the customer must not dictate the overall objective into something it is not unless they are willing to pay for your T&M to do it.
now with that said, that doesnt mean these jobs should be hacked together by any means. but liability is a major issue when dealing with vehicles.
for example, we took the bumper off my shop truck to wrap it. when we went to rewrap it, suprisingly, all the bolts fell off except one. we had no idea. we are not body shop guys and we dont know or use things like specific torque settings etc. had this been a customer car, and the bumper fell off in traffic, we would have been screwed.
its a shame we as a society have to think this way when we own a business, but alas, we do. there are ways to improve the look such as using strips cut and place in there as far as you can. with that part of the car, its hard to wrap it in one piece anyways without ghosting or getting wrinkles after it sits do to spread out adhesive.
