Dont use wd-40, It messed up my front right fender! I started with that sticker and it took it off, but I noticed it looked kind of hazy. It never went away. Washed it and waxed many times and the fender still lookes hazy and all messed up. Its black plastic on my 2004 scrambler.

I regret it to this day, But it might have just been the fact it was black plastic and was new with everything else so shiny.

pressure washer to get the sticker off, then goo gone to remove any adhesive left behind

If a pressure washer will not take your stickers off, then I would not know what to say. Well
maybe, quit useing the drive thru washers. LOL

later

 

Took the stickers off of my camo EFI wast the pressure washer , but man it took some time!!!
Its like they were nailed on!!!!!!!!! thats the first time I had that much trouble.

after I just took some gas on a rag and gave it a quick wipe.......all the glue was gone!!

 

that leaves scratches.
