Goof Off Pro Strength....be very very careful
 

My wife purchased some of this at Lowe's recently, I removed my old Boxster badge with dental floss. I thought this would be good to get the adhesive off left behind.....I decided to try it on an inside corner of my trunk first. With almost no pressure on a moistened cotton terry cloth it removed the paint instantly. If I had tried this on my trunk I would have been devastated.

Be very careful with this stuff

+1 on the Pro. I used it to strip wax off of some adobe pavers in our entryway. Worked like a champ. Fumes gave me a headache even with proper ventilation. Nasty stuff. Good on ya for testing it first.

Good move on testing first! (something that I have had to learn the hard way!)

Try Goo Gone. It's a citrus-based adhesive remover, comes in a little spray bottle. Does a sufficient job removing emblem tape.

Looks like it's got acetone, xylene, ethylbenzene, and methanol. Sounds roughly comparable to me as carburetor cleaner, brake parts cleaner, or lacquer thinner.

I usually use WD-40 or Jet Fuel/Kerosene/Diesel fuel to remove adhesive/gum from auto paint. Wash with soap and water when done.

I used that Goof Off Pro to remove some registration sticker adhesive on my license plate... it took license plate paint off down to the metal!!! I put that can promptly at the back of the shelf...

Best stuff for removing adhesive residue is 3M adhesive remover. It's about $30 a quart.

Second best is plain old Naptha paint thinner. About $3 a quart.

Sometimes, you can even use 90% strength isopropyl alcohol. About $2 at Walmart. I use it as a solvent for everything else. lol

Many years ago I debadged a 944S that also had thin vinyl pin stripes I wanted to remove. At the local NAPA I found an " eraser pad " that you chucked into an electric hand drill . The eraser pad was a light brown/tan color and was quite soft. You just pulled the trigger on the drill, slowly worked the eraser pad into what you were removing and it took the vinyl tape and badge adhesive right off with no damage to the paint. Followed up with polishing compound and everything was gone . As long as you don't dwell in one spot too long ( heat build up ) it was pretty much stupid proof .

For that I would use Ronsonol Lighter fluid in the yellow plastic bottle.

Great for removing adhesive left behind from stickers. Contains Naphtha.

Also works great for removing tar. Won't harm your paint.

If you cannot get a hold of an "eraser style" vinyl remover, it's almost easier to heat the vinyl with a heat gun (on low setting) and just peel it off...usually leaves no residue. :)
