As I see more 370z on the road, I don't feel as unique anymore, so decided to change the emblem to "Fairlady Z" to be alittle different from the crowd. (Yes you can call me naive). It's a simple DIY, but for those who really wants to do it "right", I "suggest" the following:
1. Bake the 370z emblem under the sun. (most important, makes taking the old emblem off much easier).
2. Use dental floss to slowly take off the old emblem. (search on youtube if you want to see exactly how it's done).
Result after floss:
3. The remaining residue can be removed just by rubbing it with your fingers. Some might say it will damage your paint if your car is dirty, so that's why I washed mind before I started.
4. Used rubbing alcohol to remove the tape marks.
5. Used a clay bar to clean the surface again.
6. Used car paint cleaner and then wax the area where your emblem will be.
(Some might say it's better to clean the surface with rubbing alcohol so that the emblem will stick, but I did it differently, so it's up to you).
Finally all clean and ready for the new emblem:
7. Place the new emblem as in the picture and use regular tape to hold the position:
8. Once satified with the position, start peeling off the red tape on the back.
9. Once done, pressure the emblem to make sure the back tape is in contact with the body.
10. Lift the emblem stencil.
11. All Done. Enjoy.
