get a hair dryer and heat up the badge then use dental floss to floss through the glue. once done use some goo gone or claybar to remove the remaining sticky stuff.
You will be fine. Just get the hair dryer and peel it off slowly, any glue left will come off with tar and glue remover and if theres any scratches get some polish.
Debadged gives the rear end a nice clean look! i am still undecided if i want to go to that route. But will be removing mine at some point as the badges could do with replacing.
Personal preference really but I have to say I'd prefer to leave the Accord badge on, it's a nice text in my opinion! In fact I'd like to see a "2.2" badge on it because people always say "oh is it a 1.9?" :huh: Just to clear up any of their confusion!
