Good to know. I tried using different fluids on some test pieces and windex sort of worked but the film kept lifting up again. I actually reached out to the supplier and asked about the method to stick it down and they just told me to go watch more YouTube videos.
Yup, this is why for example with window tinting (similar adhesives) you have to use an applicator fluid, and heat to get it to work along with a squeegie (credit card or etc) to get the bubbles out and work them out while its still semi fluid. or it wont work. There are various formulations like a mix of alcohol and baby shampoo, or dawn, or etc.
But also, if you already peeled it up and trying again, its ruined. you cant re-stick it down like that after its peeled or it just keeps curling up. Ive gotten that situation to work but it looks nasty post-facto. Also peeling will create a static electric charge which attracts dirt and debris. debris on the LCD surface wont hurt becuase the fluid will push it away. but if it gets on the film prior to application, thats a problem.
You have to do the application fluid and heatgun method on a fresh peice while using the squeegie to get the fluid, bubbles, and debris out and the heat allows it to conform and dry the fluid. The fluid has to be the right alcohol mix so it dries with heat as you are working it down with the squeegie without ruining the plastic film by distorting it, etc... Its a juggling act. Takes practice.
