dont use a razor blade, if you have a steamer or a heat gun itll help. after you get the tint off, use a scrubby pad and a soap and water solution. if your going to do it serious get a shop light or a self-standing flash light and really examine the window. plus if u take it to a tint shop w/ glue on it, they'll charge you to remove the glue, thats what we do at the tint shop where i work
:werd: i was guna tell him about the ammonia, but it can ruin his interior if he doesn't cover everything up well...not to mention the horrible smell he'll have for a few days. but :thumbup: window tinter?
