I bought one of those kits from Mac's for my '37 that were already pre-bent and had that black cotton-like material on them. Within 6 months, the material had come loose at all the corners on the exposed side of the glass. I took them off and cemented them back in place. That worked for a while. Its been about 3 years now, and they look like they were original parts on the car. They are faded, the material is loose, and the metal is rusting. I keep my car garaged, too.

I want to replace them, but refuse to buy the same stuff again. Does anyone know where I can get some good quality replacements that will last?
