I'm a product manager for distributor and I've tested almost all of these products on walls inside my building. the Oracal, Avery, Mactac and Arlon all gave me issues when moving their positions from wall to wall. Most pulled the paint off the wall in spots and most did not curl when leaving a white border, but all of them failed when printing and cutting directly to the inked areas. the best material i tried was a product from Catalina that is branded by GMI and other Distributors also brand it under their private label media.
