i read someone say T-cut (car paint scratch remover) can help but its not something id recommend unless id tried it lol.

Ah that made me laugh. But seriously if you want the best close to glass, no screen protector feel I recommend the spigen ultra nano. It's hardness rating is 0.2 where on the other end their tempered glass protector is 0.8 hardness.
if you go with car scratch remover get meguiars scratch x. best on the market. oh and this Is why ive had a screen protector on since day 1. prevents this whole issue
