Hahhahha, thats too funny. the good thing about DecalGirl skins (I am not sponsored by them) is that they give you time to realign, almost like re-usable in a way.
I remember skinning my original Mavic Pro with a Skin from China. It stuck like S**% to a blanket. You had one chance to line it up and if it was wrong, it wasn't coming off.
It added about 2kg to the weight of the drone with the amount of glue they applied to the back of the skin.
