iphone lcd oca refurbish / repair

hi guys,

ive recently started replacing the glass on iphone 5/5s/5c lcds using oca,
the machines im using are an autoclave and a laminator,
just wanted to see if anyone else on here is doing the same thing,
looking for advice on applying the new polarizer as the old one gets scratched and doesnt look great, look forward and welcome anyone to post anything about oca refurbishing, will be good to share tips and advice, thanks 🙂
