Default Removing Scratches From A Screen.

Hi, guys. I noticed a small scratch on my LG G3, it's small enough that you can't feel or see in normal use, but in the sunlight it becomes noticeable. It's just something that's irritating me. I was wondering if anyone has had any experience with any DIY scratch removal methods? Also, I just purchased a Spigen screen protector. Do you think the screen protector will conceal the scratch? Thanks in advance!
