Last fall when the front porch got a new roof, the guys removed the storms for the Pedimented Window. The storms didn't get reinstalled because they needed some work first.
The oldest of the glazing compound was failing and the paint was starting to peel. Over the past couple of weeeks in the down periods waiting for varnish to dry, etc on the the back door, I scraped, sanded, and removed the glass from these storms. Of course, when removing the glazing compound and glass I broke one of the panes (the one I'd replaced last time, I think. Its putty was in good shape but I figured I'd do a full restoration...). Fortunately I had a piece of glass that was big enough. It just needed to be cut down to the correct size.
Over the weekend I started the next part of the process, including final sanding, primer, and re-installing the glass. All the glass is bedded and pointed, but only one of the storms has been completely puttied. The other one will get the exterior putty sometime this week. Then I wait for it to skin over before final coats of paint and re-installation.
I'm using Sarco putty this time. It's way easier to work with. I highly recommend it.
