I had to pull the tint on my truck b/c a ticket and not wanting the points. I cant really help that much with the defroster lines but as for the rest... a tint guy told me this... The best way to remove it was in the whole sheet use a razor blade to peel back one of the corners and with stead pressure pull it off like a big sticker then use allot of soapy water (dish soap) and that same razor blade to scrap the glue off. worked great for me didn't scratch at all and they came clean ez but i still would be careful with the blade. As for the defroster lines I would try slow and steady with allot of the soapy water to try and break down the glue. Either way let us know how it works when you get it off hopefully another member can give you better advice on the defroster lines. Good luck
