Hello and thanks to everyone who responds. I recently found this forum and am pleased with the wealth of knowledge available to me. My question is for the treatment of aluminum after being etched or ground down. I see modern wall art pieces the people say are "pure metal" and "hand ground" to get different textures and light reflections. I want to take aluminum sheet and make a large piece of wall art that is ground and sanded to make a unique look. My main question is can you grind and sand bare aluminum and leave it be?? I know aluminum oxidizes and usually gets dull. So is there a special kind of aluminum needed to do this and keep a bright and shiny finish, or do I have to clear coat over the aluminum after the process is finished to keep it looking sharp? I have only worked with steel, so I appreciate any knowledge you may provide me here regarding aluminum.
