Yeah, you won't get it off.. it would have likely ruined the laquer. If you really want to try, you could give it a going over with a machine incase you are lucky... but if you are inexperienced and the laquer has peeled or been "burnt" then you could make things worse..
I would simply sticking a GTI badge on again and wait until you can have the boot resprayed (I'm sure a "smart repair" would do the trick but the quality is always hit and miss).
