We're looking for something comparable to DryTac WindowFX with a decent price tag on it. Use will be decals for a window Mfgr on their in-store displays, they want them crystal clear and removable and specified an adhesive PET film or something similar, maybe because it's more rigid and easy to install?? They didn't like the pricing for WindowFX, tried GlassAdhere, loved the price, didn't like the product... It'll be uv printed. Any suggestions from anyone on an alternative?
