wet or dry

I have a 4foot by 8foot inside sign to do, i am using 3mm gloss black e-panel as a substrate. customer wants sign lettering done in Chrome (yuk) but anyway, this customers logo is 88 inches by 21 inches and has to be done in one piece. I have never done one that large before, not that that really bothers me, but I am wondering if I should apply this dry, with putting a piece of tape in the middle and laying down one side at a time, or should I do this wet, using an application fluid. the rest of the sign can be done in pieces.
any thoughts?
