My iPhone 6s has this after market spray on scratch resistant coating which I got done a local retailer and I don't have any heavy scratches per say thanks to it. I can however see this micro super tiny hairline scratches which weren't there before. I wondering if you can get coating scratches but not really scratches to the actual glass? They are only visible on certain angles. Why am I asking? Well because you purchase after market anti finger spray on coating which the iPhone already has. If I buy this and apply it I wonder if it will fill in those 'coating' scratches assuming that's what those are.
