Vinyl wraps use a different type of vinyl than what is used for everyday signage. It is specially constructed with air release channels on the adhesive side to allow air to be squeegeed out from behind it with great ease. It is also repositionable which means that you can pull it back up and lay it down with ease. By using a heat gun you can stretch it to amazing limits. I have wrapped motorcycle tanks and hard hats to name a few austere shapes. Oracal vinyl is what I strictly use and it is guaranteed for 10 years. 3M is only guaranteed for 7 as is Avery.
For a test, I took a 24X24 piece of digitally printed vinyl and wadded it into the size of a softball. By carefully peeling it back open and then using a heat gun, all the wrinkles came out and it returned to it's original shape and suppleness. Amazing stuff.
Oh by the way, you can remove it without any adhesive sticking to the surface for up to 4 years.
