Hi! I have a 6'x3' half round panel I have to make that will go above a church door. Do you think that Strong Line Steel Reinforcement or restrip would be enough to hold it considering that the door will be continuously slammed I would imagine and the vibration will probably stress the glass? Also another concern I had is due to the fact that the window has a curve, I will have to use lead, as opposed to zinc U channel (I do not hve a jig to bend zinc). Would that be strong enough to hold up such design?
