i took mine off the week i purchased mine, if i were to do it again i would get a heat gun, fuck a damn hair dryer lol i went through two of them. Seeing as you have to always keep it hot so it does not cool off and break and plus i was the only one doing it with no help it was a PITA! And I used 3M adhesive remover to get all the glue off the car. Mine were on there since the previous owner purchased it so they were faded, I would recommend depending how long they were on there to get it wet sanded, it will defiantly help the paint out.
