We used IJ180-cv3 and 8518 laminate. Some might say it was overkill, but I didn't want to be out there again due to failure. I am not out there installing today, stuck in my little hole cranking out more things to print - we wrapped some walls in a skating rink two weeks ago, and learned a lot about how to keep things easy. Since this will be viewed from the ground, I ran seams every 52" - it saved a ton of vinyl, and makes installing in a two man lift a lot easier. I still used about 30% more vinyl than I had anticipated due to lamination problems, and gaps between prints and overlaps. Next time I will be sure to charge a little more for waste... that stuff isnt cheap! I might even sub out the prints, this thing dominated my printing time for nearly a week.
Thank you for all the compliments. I will post more pictures as the guys send them in. It's nice when a client says they are happy to have spent the $$..
