How do I remove the Civic and DX logos from my hatch?
 

Are they just stuck on with double sided tape?

Most likely the logos are held on there by tape,strong one at that. So here's what to do. Use a heat gun or hair dryer to heat the logos for a minute or two.Then use a piece of floss ,like you would normally floss and slide it behind the logos .Use a sawing motion and It should come off. Double up the floss if you have to. Use adhesive remover to remove any adhesive left behind. Good luck.
