I had a GT2 wing shipped (UPS) bubble wrapped and boxed, but something had pierced through the box and scratched it. How about getting a wooden crate to contain it, knocked up out of some old pallet, and then pack it bubble wrapped, tightly packed with scrunched up newspapers? (Cheap softwood shouldn't weigh that much and won't pierce like cardboard, extra shipping cost is probably cheaper than risk repair / respray)!
