yeah I was wondering about that, same with some of the stains on the other stuff.. im curious though if I rub it could I throw off the level surface and make a low spot? Maybe I'm over analyzing..
and it all started just trying to find a decent bandsaw, and I couldn't let it all go...
naw no way. thats hardened steel your talking about. there isnt very much you could do to damage it. rub away.
