This is something I have been wondering about, how good is good? I have mostly only seen other peoples metal work in pictures, and they look great. In pictures of my own stuff it looks good, but when I actually look and feel of it in real life it would be good enough for paint but I would not think it would be good enough to polish. I like working with aluminum and my racecar past almost always make me choose to use light (.040) which makes me ask, can you use to thin of metal for a part with lots of shape because lack of thickness for filing versus trying bring every low and high into compliance? Couple of pics visual confusions for me.
