Yea displex is way to apreasive for plastic. This apple sauce is good. I had scratchs from my school ID digging into it in my pocket while I was skateboarding across campus. They were perty deep. I might be buying a 25 dolar replacement screen of ebay. But yea gave it a better then new shine I think lol. It does what it suppose to and that is to polish. Kit is like 20 bucks and comes with everything you need. O and make sure you have a flash card to cut up to get the polish out of all the cracks when your done
