Overall , the finish is barely noticeable and it does live up to the scratch free guarantee . I personally have taken a key and pen to test it without any resulting scratches , whatsoever . There is a slightly tacky feel to it , which some may like as it does offer some slip resistance . Unfortuantely , it also seems to hold onto lint , dust and whatever else I have in my pocket .

Question: What might happen if you treat the case with some resistant liquid to make it less tacky ?
Answer: It will come across as too polished and cleanIt will not hold onto lint and dust and will have a smoother finishIt will slip and fall from many surfacesIt will not be as easy to grip or hold onto
