Removing Tail Badges

I removed the CLIO badge a good while ago and what a pain it was. Every car I have I debadge the rear but this was unbelievably difficult to get all the glue off.

So last night I was washing the car and decide the Renault Sport badge is going to go and i'll have it completely debadged at the back. Picking the letters off was the easy part then "aahhh why did i do that".

Honestly what do they use - Superglue? :think:
 
It has to be tough clue to keep letters attached. It has to be , car machine washes.. -40celsius or +40 celsius, winter.. rain.
