That was the original reason I was working it over, Jim...the bond HAD been broken in most areas and so it was totally unsupported by the frame in places. I guess it was due to 40 years of drying out lol. (And I dont think were EVER supposed to tell Bjorn he was right!) Poncho, I thought about replacing the putty with some sort of adhesive/putty, but thats when the idea of spot-welding it struck me as being more permanent and more easily hidden. Jim, that makes sense and Id figured the putty allowed it to expand and contract somewhat without binding it up, but I also figure thats why it eventually broke loose from the frame. It was pretty bad in some spots...there were different-sized gaps, some were at least 1/4".
