hubby keeps forgetting to bring heat gun home from work so I have been picking it off( been my nightly break activity lol). it was a thick silver shiny decal. got it down to the size of a quarter. need to pick up some more decal remover. it wasnt an auto decal so it's really stuck on there. all my others came off no problem. right now my jeep is naked. took off all factory stickers and ordered new onesUsing heat? I have a couple on mine I need to get off but think they have been on so long it's hopeless.
