I need to replace my old M6 badge with a new one (previous owner stuck it on the wrong side for some reason and it's also quite faded and starting to peel.) Anyways, what's the best way to remove my old badge? I've read that people use a hair dryer to soften the adhesive, before working it off with some dental floss. Unfortunately, I don't have any power outlets in the garage that the M6 is parked in. Any suggestions?

Assuming that it is the trunk lid badge, suggest using dental floss and dish detergent. You don't want to heat it.

Maybe try some of that "Goo Off" made for removing label adhesive, just try some on a hidden spot of paint (trunk, engine bay) to make sure it doesn't "haze" the paint.

Thanks for the suggestions--I'll give the dish detergent a shot (don't have any Goo Off at the moment.)

Be careful of goof-off; I think that the warnings on it or goo-gone say not to use on single stage paint (non clear coat). I would suggest parking in the sun and let it heat the adhesive; you may then be able to twist the M badge to break the adhesive bond. Also, if you use floss or monofilament line, do not hold the line against the paint but use it against the back side of the badge. In otherwords, pull up on the line away from the paint and avoid holding it down and wraping around the deck lid. This will keep from having saw marks in the painted surface.

Alpinacsi may be right about "Goof-Off" (that's why I said test it first). I was trying to think of a petroleum based product that might help soften the adhesive, so a better idea might be to try an automotive tar remover. It is made to be used on auto paint.

I think you will find the dish detergent will remove the adhesive residue after giving the area a good flossing.

How about lighter fluid? I've used it to remove other sticky residues on other surfaces--like the airbag warning stickers on my visor when I had an E46--will it harm the paint?

If its original paint I would use a hair dryer and plastic scraper very thin. If its a repaint I would use mild detergent and the hairdryer.

The floss will cut it off. I have used brake cleaner on a rag to remove any adhesive left. Use it sparingly. It won't hurt the paint like carb cleaner will.
