Ok I know heat will remove the Tint and adhesives may be left behind.I went light in Nov and now want to go darker.Although Tint Shops aren't charging to much to remove tint I rather save the $100 - $175 for tint removal and put it to a quality film.I have something that should help get adhesives off the but do not what to risk messing up the defroster lines.Will non scratching scotch brite pad be good to prevent damaged to the defroster lines??What are the do's and don'ts??
