I shipped the "pass it on" windshield a couple months ago and it was done in plastic wrap then bubble wrap. All was well. FedEx person told me it was actually less likely to be damadged, because they could see what it was. Put the shipping lable right on the wrap and sent it.
As a trauma nurse for 15 years, I have to agree also. This injury is treated just like a very bad burn and rated in the same way. Glad you are doing well. Good advice from ole Puc there too. Take care!
