As some of fellow SXZ owners I have removed both front and back factory antishatter films as they were dust and scratch magnets. I was enjoying the improved clarity of the screen and premium look of the phone, but the only thing I was missing was the oleophobic coating. Well, I have ordered GLAS.t Slim, but it it will take some time to arrive, so I decided to experiment. While in the supermarket, I just sprayed a coat of some random nanotech spray car wax on the screen and buffed it with a microfiber cloth. Also I have cleaned the screen first with some glass cleaner. Well, guess what. I now have an oleophobic coating on my naked SXZ! Finger glides perfectly on the screen, prints are very easy to wipe even on jeans and smudges don't appear as easy. So I would suggest the following procedure to get a fully working durable oleophobic coating on our SXZs:
1. Use a good glass cleaner spray to thoroughly clean the screen
2. Spray a coat of nanotech car wax (comes in a spray bottle and advertises a protective coating), buff with a microfiber cloth while it's wet. Repeat 3-5 times.
Will have yet to figure the best car wax brand for the purpose of creating a lasting and durable oleophobic coating, but for now this random stuff works wonders. Will probably buy a bottle next time I'm in the store. Will use it on my car too.
It's like $3 smth.
Please post what had worked best for you.
