Hi guys. I'm starting to etch aluminum enclosures and I've seen, after extensive research, that it's a must to perfectly sand the face that will be etched.
So I've run into a few problems/questions, and as I didn't found answers elsewhere I've came here to ask you veterans. =)
1- How do you achieve a perfectly flat surface? Do you use sanding blocks, orbital sanders, etc.? How long does it takes?
2- Is wetsanding better than drysanding for aluminum enclosures? Why?
3- How do you get a reflective finish like this one below?
Any other recommendations will be very much appreciated. Thanks!
