What vinyl for temporary automotive graphics..?

[Truckntran 0]

What are folks using to put temporary graphics on new cars like the vinyl prices you see at the dealers? How long can it stay on safely? mANd can it be removed by dummies or would an experienced pro be needed instead of letting the dealer pull it off?

I did up my truck for a santa claus parade using Oracal 631, loaned it to a buddy of mine to drive for the parade, and before I could get back the next day to do the removal he had ripped it all off and not a scratch on the truck, so I'd say yer pretty safe with it. And it was cold outside, had been parked outdoors all night.
