I tried absolutely everything from mineral spirits, goo gone, blow dryer, finger nails, pet. jelly, ect. Went over to autozone and picked up a $4 can of oops and tried it today. Took less than 10 minutes and it all came right off. It left a little bit of a haze. Took some armor all wax and gave it a waxing and it looks like it did from the factory. OOPS is da chit!!! LOL Here is a pic of the tailgate.
