If the argent was applied with a spray can it should come off almost immediately with that stripper, and short applications shouldn't do anything to bother the anodizing. Its actually pretty hard to remove anodizing, I had to sand it off of a clear anodized aluminum motorcycle rim (the anodizing was old, yellow, and damaged in places), and I couldn't come up with an easy chemical process (and I tried the stripper!). I just mentioned it because of the small possibility that if you left it on for hours it might somehow mar the finish, although that hasn't been my experience.
