I use the Monster Clean Screen kit. I have some very slight scratches you can barely see in direct sunlight but I am very **** retentive about my "Blu". I've used PhantomSkinz on my smartphone and it works perfectly. The material doesn't hamper the touchscreen sensitivity and actually has a slight "healing" property which slowly fills in light scratches. I'm thinking about buying some in bulk and applying it to my nav screen. There are a couple of companies out there (Nushields for one) which sell precut shields for our systems for about $20. I just wanted to hear if anyone has done this yet.
