I have a small commercial aluminum cake pan with the welded corners and was thinking of using it for an amp project. The pan has a logo (Magic Line, if that is important) stamped on the bottom of the pan. Used as an amp chassis, the logo would be dead center on the top plate. I don't think I can have a transformer or tube socket in that logo's location with this amp. Would judicious sanding and Rust-Oleum hammered texture paint be sufficient to obscure the logo or would it still be visible through the paint? If the logo needs to be filled in to become invisible, what would be the appropriate filler to use with aluminum? Or do I live with it?
