Sticker Removal

I know this has been asked a million times, but I pulled off the Vmax sticker on my motor. I has left behind a hard coating. I have used some sticker removal stuff but that just doesnt seem to cut through it. What can I use to remove the stuff and wont damage my paint?

Try Super DeGooper. You can get it walmart or home depot. about 4 bucks for a little bottle. This stuff is amazing! Got rid of all my glue residue on my boat for the carpets, and all of my stickers too!
