Wouldnt cheese wire it to be honest mate, thats the right idea but you wanna try and find something a little less course..

When I removed all the badges and side strips from my old XR3i I think I used a bit of fishing line, but go careful you dont get to close to the paint cos you will scratch it!

Once you've got the badge off very hot water and keep soaking the blakc guey stuff and it will start to melt, once thats done you should be able to use abit of compound to rub it off and then just polish it up again!
