Would be interested to hear from a chemist on this.
Highly unlikely, there was probably some impurity in the alcohol used. Isopropanol will evaporate with no residue. Remember your coating is NOT aluminium but aluminium oxide, an enert unreactive matrial. Powdered aluminium or even metalic is different.
