Hi, recently i bought i used Ryumon katana (DH real hamon), its still in excellent condition exept for some very tiny scratches and some signs of rust spots, nearly mirror finish. Allready cleaned/polished it, but still there. I read that Metal Glo is really good in removing these things if yes, how do i use this and how much. Does Metal Glo harm the blade (surface) at all ? some pictures klick

Well metal glo is a fine abrasive polish, it does fine in removing rust and very light scratches but I've heard some report that it removes hamon (I recall using it couple of times but the hamon is still here lol). Metal glo has almost same abrasive property as Flitz (if I am not mistaken)
Having that said, there are less abrasive polish out there like never dull and noxon 7 (least abrasive). Depending on the level of polish on your blade (talking of high grit polish here), metal glo does alter your polish But then again metal glo is much more effective in removing very light scratches compared to Noxon 7. Given that your blade is near mirror polish, it should be okay using metal glo.

Mothers Mag and Aluminum polish is a paste similar to Metal Glo but has a finer grit, as it is made for softer metals ( magnesium and aluminum ). A dab of it on a clean rag and gently polish , or can be used as a finishing polish after the Metal Glo ( the Metal Glo may slightly dull a mirror finish )

Isn't a true hamon all the way through the blade that thats why you get them super polished so they can be brought MORE out then removing them? Now, I know that an etched hamon can be taken off with polishing as it is just a surface "scratch" made to look like the hamon? As to the original question. I personally use auto body sanding papers, different grades, to polish my swords. But if you just looking for a quick polish job, then that should be fine to use. I use "Blue Magic" metal polish cream for taking gunk and such off my sword, and is the last step for my in depth polishing method. After I take the 1500 grit paper to the sword, I just want to buff out those final scratches with the cream. Get a mirror finish every time.

The hamon does go through the blade and it is always there but the visible hamon can be dulled or completely obscured by using the wrong polish or polishing techniques.

Big stones or sandpaper: from the spine towards the edge. Never circular motions. Small stones, small pieces of sandpaper or small dabs of paste: along the blade in small movements.

Metal glo can and WILL remove a false hamon, especially if its a fine wire brushed hamon. I know because I did it lol. But, honestly, if a sword isn't DH, I'd rather they not even bother with a false hamon.
You shouldn't use metal glo too often on a sword, as it does ever so slightly alter the surface of the steel each time you use it. So don't go at it over and over and over trying to get rid of those scratches. If they really bother you (which I totally understand) I would suggest trying to find a professional who could get them out for you.
I was unaware that metal glo can obscure a genuine hamon. its always been my understanding that a real hamon will become more prominent and beautiful with polishing, although I suppose that could be referring to REAL, traditional katana polishing. I have a sword with genuine hamon that was enhanced with wire brushing, so I used metal glo to try and get rid of the wire brush scratches and leave only the natural hamon exposed, which worked to some extent. The result wasn't quite what I had hoped for but I like it better than before.
