What exactly do you mean?Its better to roughen up the ali surface with sand paper or other abrasives at least 240grit. Then clean with acetone and bond within a few hours.By etching I mean using chromic acid to roughen the surface a bitSanding would be easier and faster imo, Degrease first with acetone or degreaser, use fresh cloth after cleaning everytime till you dont see any more residue on your cloth, that way you are sure no grease or silicone or whatever is left on your plate THEN start sanding, otherwise you will fill the scratches with grease if it hasn't been cleaned before. then degrease and clean again. I would go for a 80 grit to leave some scratches and to be fully sure take a knife and raster is with the knife for more mechanical bond.
