Well I finally removed the Genesis name plate on the back and replaced it with the winged logo.
TY for all the suggestions. It was so much easier once you have the right tools. I did not even used a heat gun.
TY LQQK. I used the 3M adhesive remover on each letter, let it soaked for about 30 secs, wiped off the dripping excess, and used a fishing line. It came off so much easier than I expected. After removing all
 the 
letters, I removed all excess adhesive, wiped the area clean, applied a glaze and sealant. The dried the area completely. I used a Dremel tool to remove the 2 posts in the winged 
emblem ( because it was the hood 
emblem).
Finally, I lined up the 
emblem the way I wanted it, used a level and centered it and viola!
it was awesome. Just like the 2021 G70 backend just 
emblem and I love it.
