Hi
I understand the scratch thing but have you tested the screen to see if the Oleophobic coating has worn off ? You can do that just by putting a single drop of water on the screen, if it stays almost in a sphere shape then it hasn’t worn off. If it just splats onto the display and does not form a sphere then the coating has worn off. You have two options. The first is to do what you are doing with the product you have bought or you can put on a high quality screen protector, the more expensive ones usually have an Oleophobic coating of their own.
If the coating has worn off and you wipe on a new one I doubt it would make the screen worse but just remember that when its done at the factory its baked on after its applied and normally lasts one to two years. If you re-apply it yourself it may only last a few months and will need to be done again.
The chemical makeup according to the patent made by the inventor at 3M is as follows :-
“Hydrophobic and oleophobic coating composition, which comprises the following components based on weight percentage: 0.1-15% of a fluorosiloxane, 1-30% of a polyacrylic resin, 0.1-15% of a silane coupler, 33-98% of an organic solvent, and 0.05-15% of an acid.”
Personally I would go for the screen protector, but give the product you have bought a shot and let us know how it goes.
