I'm not Hammered but it is just a decal. Use a hair dryer/heat gun to soften up the vinyl then use a razor blade to start it peeling, it should pull right off. If not, you can always use one of the 3m eraser wheels.
I used a Heat gun (black & Decker) and it was gummy as all hell. But It came off. I was really happy to get that blue off there. Looked stupid on the red if you ask me. I used some wd 40 and my thumb with a rag on it... took some effort, but once you get the decal off its 50% gone. the sticky stuff is the hard part.
