Just noticed that besides the glass setting tape there is a 1/2" wide piece of foam rubber encased in cloth that sits in the groove underneath the glass. I noticed the vendors don't appear to make mention of this item. I'd imagine I could match some window/door seals at Lowes. Also what should I use between the horizontal stiffners and the outer sheetmetal. Originally it was a tar/foam substance. Would spray foam do the trick or is there an original item I should look for?
