How to get rid of scratches on a zippo lighter?

I just got this zippo lighter called,"lucky Ace" but i accidently droped it and made like 2 or 3 scratches on it and there like 2 and a half centimers long how can i remove those scratches?|||You can try some very fine buffing compound and rub the compound gently into the scratches, if they are any deeper I would send it back to the Zippo manufacturer in Bradford, PA. Zippo usually guaranties their lighters for life.
