Debadging

To remove the badges from an E30 is a 15 minute job and cleans up the back end of the car in my opinion.

What you need is a piece of string or fishing wire, some rubbing compound, some polishing compound, some tar remover and some polish and rags and a kettle.

Boil the kettle and pour the hot water slowly over the badge, this softens the adhesive.

then using the string in a sawing motion get behind the badge and saw away the badge

now you will be left with the partial remains of the adhesive.
