If you mean the GT Badge, in the past i found the best way to remove the adhesive is to GENTLY heat it up with a hairdryer whilst slowly lifting one corner. The other way is to use some fishing line or the thickest dental floss you can find to saw though the glue. Which ever method you use just remember to clean the excess gunk off the paintwork before applying the new badge. WD40 is good for getting rid of sticky stuff
Sorry misunderstood Once you get past removing the boot trim, the rest is pretty easy. But its best to wear gardening gloves - well thats how i felt last time i removed one
For me, i could not live without a rear wiper. On a previous car (2007 Audi A3) the rear wiper motor failed and i wasn't able to replace it for 4-5 days which coincided with 4 days of pretty much solid rain. Don't do it!!
