Yes, that was interesting. I don't have time to search right now but there was a thread on here about it. Was that you who brought it up the first time, John?
That was about making actual space mirrors of aluminum I think...prolly need to go way past 400-grit to get to the ink stage, LOL. And man, what a mess I bet it would be.
