We think this is the original fender welt in our 1953 Buick2 door hardtop Roadmaster – trim package number 72. It consists of what appears to be an aluminiumor steel tube which is split the entire length (8 – 9 feet). Inside this tubeis a fabric covered wire that runs the full length with 1 inch teeth coming outof the split every 3 inches. There wasfabric between the teeth. A very smallpiece has not rotted away and is photographed here. The fabric covered teeth fit between the fender and body ofthe car. The tube does not appear tohave any paint or finish on it. Theteeth are wrapped around the fabric covered wire. I have never seen this before. Can someone tell me anything about it? The car is nearing completion and I intend topolish the welt and put it back in the car. Any and all help / information is appreciated.
