Q. I have lots of questions and I’m afraid I already know some of the answers (no shortcuts) but here goes: We bought a 1978 house that has aluminum track, 12 over 12 windows. The glazing on the windows has failed on all sides of the house and needs replacing. The thickness of the glazing bead seems very narrow. A glass pane has already fallen out and it appears that there were no points to hold it in place. In the spring I will remove the storms, scrape out all the loose stuff, and reglaze all the windows. Should I prime the muntins with Kilz first, or other prep?
I have done glazing before so I know it takes time, but to do 24 panes per window will take forever. Is there a shortcut or a new product that is easier to apply than traditional glazing? It strikes me that the narrow beads will be harder to get nice and smooth and straight than the thicker beads I am used to. Any tips? And why did the glazing fail so quickly?

The inside lining of my microwave was peeling so I pulled off all the peeling plastic and it still works fine although it is kind of ugly inside the box. I think the lining is basically cosmetic.
