Similar but not the same as there doesn't seem to be a layer to scrape off is Crystalusion Liquid Glass. I've had it on my phone for about a month now and used it on my previous One X for about 6 weeks before I stopped using the phone. It's a one shot application that lasts around 12 months, they say. Application is two wet wipes, one to clean the phone and one to apply the liquid glass. You could do 2 or 3 phones at the same time.
Now I'm highly skeptical but it's not right expensive so I thought I'd give it a shot as hate those plastic screen guards. I do a manual job in dust, dirt, grit and all manor of ****. Phone screen is still pristine after a month of use. Treated the mrs's iPhone at the same time. Compared to another iPhone in family her screen feels a little bit slicker now. Supposed to be anti bacterial and does make it easier to remove grease, sweat and fingermarks
I was going to try some Liquid Armor but difficult to get in the UK when I looked. Crystalusion seems to work. Don't get me wrong I do look after my phone and carry it in a pocket on it's own. Dust, grease and grit I can't keep out of said pocket all the time. It may well be snake oil but currently don't seem to have wasted £7
Time will tell for sure. BTW you can treat the whole of the phone though care has to be taken not to get liquid into the phone of course. I also shall not be doing a drag test behind a motobike
PS. It can't be removed as there seems to be nothing physical to remove and also does not affect screen clarity. Got to admit it sounds like I've treated my phone with 2 expensive baby wipes
