Geez, take your car to a real shop will you?
You almost have to do it on purpose to fugg that step up.

 

Peel it off with some hairdrier heat
and remove the residual adhesive with elbow grease
and some paste wax. The petrolium distillates in the
paste wax will safely remove the offensive adhesive.
Maybe it wont have been on there long enough for
the surrounding paint to fade enough not to notice
the unfaded paint under the sticker...

Pascal, how do you tell a real body shop from a bunch of fuggers?

 

Go randomly to a bunch of them for a bogus estimate and look around while you're there to see if the cars being worked on, look good to you.
A long time restoration shop is usually a good shop...

I mean, if they can't clean a windshield with a razor blade without scratching it, I wouldn't let them sit in my car.

 

It also depends on what kind of sticker/adhesive it is.

I bought my car used from Car Max, and they had their lettering on the back of the trunk. I "accidently" took them off with a pressure washer. No faded paint or glue was left.

My girlfriend put a bumper sticker on her car. When she sold it she had me remove it. (*Note "had" instead of "asked" :P ). I was about to use goo gone or whatever it's called. I peeled it off no problem, and what little glue was left I just rubbed off by hand. Product was not necessary. No faded paint, but then again, it was on there for probably less than a year.

Also, I could have been lucky with those. I know length of time adhesive is on a car is a big factor, plus the type of sticker, etc.

 

My bottle of Goo Gone does not warn about using it on cured paint. It says it can remove wet paint, and warns not to use it on silk, leather, suede or rubber.

It also says not to treat clothing while wearing.

Maybe they changed the label, changed the product formula, or have more than one formula.

+1 on reading the label, preferably before you buy the product for a specific purpose. Always test on a "hidden" area.

 

Denatured Alcohol will also remove the adhesive and wont hurt the paint. It will however strip wax off the car.

 

When in doubts, use wax and clean remover (prep cleaner, whatever).
It will never hurt the paint...

 

A clean, straight razor blade should NEVER scratch glass. If you live in a state with inspection stickers, they use a razor blade to scrape off the old one every time. Also, I've used goo gone to clean up residue on paint many, many times. Never had an issue with it. Just remember that it pulls off wax as well, so a new coat wouldn't hurt after you use it.
