Last year with the iPhone X, it was said that the Silver color with the polished stainless steel bands was better for scratch buffing since you could just use a standard buffing cloth and solution just like you were buffing out scratches on a stainless steel watch. The Space Gray version had some kind of black plating on it so if you got scratches on it, that's it (cannot be buffed out). This year with the Gold, has anyone mentioned if scratches can be buffed out like the stainless steel silver? or is it more like the Space Gray with a plating on top? I'm trying to decide between silver or gold. The Apple leather case leaves the bottom exposed so I'd like the ability to buff out micro-scratches later on. Thanks.
