found this under the silicone. he (she?) does good work. original silicone job lasted 21 years and I probably could have gone another 5 or 10 or maybe even another 20, but no point in waiting for a leak to happen. I had a few spots where algae was working it's way under the silicone and if I do it now I don't need to worry about it being in between the panes.
thanks for the good work Pat.
