What options are left?
You can try to find someone who can airbrush. That looks nice but its rather expensive.
What I did. I found a high-res picture of the gaint logo. Send this one to a carsticker company in your country and paste it back on.
Car stickers are only 5$-10$. So its the cheapest and best option!
Find the stickers here:
Now the stickers are cut out of some kind of sticker-foil. You can choose from a given amount of colours. There is no need to change the pictures colour.
