I was taking the AR layer off my PSone screen and picked up just a leetle edge of the polarizing layer, so I put it back but it has like air bubbles under it and I can't get rid of them?
Myself and several others on the Diy Projector site at LumenLabs pioneered the method of removing Antiglare from polarizers several years ago. And in the course of learning that technique we also heavily explored replacing polarizers when they had to be pulled off because of botched Ag removals. After hundreds of dollars and many months of testing we could not find a practical way to replace the polarizer.
See the factories do it in a clean room using very sophisticated machinery. There is just no way to duplicate that at home. So you will ALWAYS have trash under the polarizer or air bubbles , etc. And the polarizer costs around $50-$75 for a small sheet. Which is very unpractical.
