Chrome can be stripped in the reverse of the chroming process, if this can be done on aluminum alloy I am not sure.
i was using sandblast as a general term. walnut shells, glass bead, silica all can be used to remove the finish. the powdercoater should be aware as to what media would need to be used. the powdercoat needs to adhere to the metal not the chrome . if its attached to the chrome and the chrome peels the p/c is also peeled off. if its attached via the method used in p/c it doesn't peel off rather has to be chipped off as it becomes extremely hard after the baking process
