This isn't the only way to debadge a car, but I found this one to be very easy and fool-proof. I'm sure there are many more writeups like this one out there (perhaps even here), but I hope that this will help someone despite that. Please, be careful. You can easily damage your paint if you're not careful.
- Hair dryer
- A few rags (microfibers preferred)
- Light polishing compound (I used Dodo Juice Lime Prime, it did the job this time around)
- WD-40, or some sort of goo-remover. WD-40 was the only thing I had around.
- Dental floss
- Some sort of tool to safely remove remains (I used my nails (not recommended and a clay bar to remove the very last remains of the glue)
- Car wax
Start by heating the badge you are about to remove. Be careful, as you can easily overheat the paint causing permanent damage to it. 10 seconds or so should to the job, but please be careful.
Spray some WD-40 (or chemical of your choice) on the badge. A smart thing to do is to place a cheap rag underneath the badge to prevent the chemical leaking over everything.
Heat the badge for another 10 seconds or so. This should loosen up the glue, making the next step that much easier.
Take a decent length of floss and go to town on the badge using smooth motions. Be sure to grab the badge when it falls!
After the badge has been removed, you most likely have a bunch of glue remaining. The first time around, I used an old credit card to pry the glue. You can also use your nails or anything plastic (and not too sharp) you have around, but you can easily scratch the paint if you‘re not careful.
After removing most of the residue, I removed the smallest particles using my clay bar.
Now you‘ve exposed paint that has never seen the light of day, and it will show. You need to even the paint out using a polishing compound. I used Dodo Juice Lime Prime this time around, as the paint didn‘t need a lot of polishing to even it out.
I would recommend washing the area afterwards. Doing this, you‘ll be able to see if your polishing did its job or if you have to do more. Afterwards, wax the area and you‘ll be done.
The end result:
