How do I etch aluminum?
I've been searching and reading on how to etch aluminum. I've tried the photo paper toner transfer numerous times, but the toner does not stick to my aluminum plate. I've gone over with my iron so many times while putting extreme amounts of pressure on it, but no matter what I cannot get the toner to stay on my aluminum plate. Can someone please help me, or let me know a better way of doing this!! Thank you!
