I don't think you can get the kinda shine that you get from a paint job, but since I got gloss it's probably as near as you can get.
I have used the buffer and I have used different waxes, I haven't polished it yet or used any twin pack sealers, though the finish isn't that bad.....
I would definitely tell them that the car is wrapped and to go careful near the edges or any seams, even catching the wrap with your nail can mark it, though I have been told by the chap who put it on, that you can buffer out light scratches !
Don't get me wrong mine is not covered in marks, I have been very careful.
