New Wisker Material?

[garymand]

I'm in the middle of re-gasketing my doors and one of the window wiskers cloth overlay is sun rotted.  Is there a newer type available that will not fad as fast and completely deteriorate in ten years if driven in te day time?    I also have to reglue the guides.  I have the old felts in good shape.  What is the most current process?  The manual says epoxi the felt to the guide then epoxie he guide to the window.  one note said rough the glass?  Is this anouther 10 year maintenance feature? :'(
