I cannot vouch for steal rubber, but did use LMC. Replaced rear window, windshield and all door rubber. Door rubber was the only rubber I wished I had done more research with prior to buying. Local glass guy made some recommendations and had opinion on the door rubber specific to quality, fit and installation method (glue). I was able to use some rubber he had that was more robust, fit better and had a metal pinch piece that eliminated the need to glue. I believe I will also be able to remove the door rubber if I need to (for paint) and reinstall. The glue-in method required for the LMC rubber would not allow that. Windshield and rear window rubber - no problem.
