This is WRONG on so many levels! But I'm sure the stores want to sell this new product. this is trying to re-invent the wheel. Why do you think that those old monks did the same process for centuries? Because they were dumb? Because they figured out that the LEAD will expand and contract with the weather for ONE thing. And when you are assembling a lead piece it is supposed to be loose enough to be able to make adjustments BEFORE YOU SOLDER, so this way, it is rigid before you even get the whole piece together. This is so wrong. The applying heat to the glass also doesn't make me feel comfortable.

It would be helpful to see what the glazing strip looks like - a decent, close-up shot of the strip.

Never saw what the NO DAYS GLASS is. ???
