Matt, There are many products out there for rubber but I would urge you to avoid any of them with silicone content. My personal preference for the task you describe would be multiple coats of Meguiar's #40 (professional line - tan bottles) for rubber and vinyl. I love the stuff and use it on all rubber (including tires) on ALL my cars. Wayne Date: Sat, 13 Sep 2003 07:45:15 -0700 From: "jennifer allyn" <gearhead.girl@xxxx> Subject: Rubber Renew? I have an NOS piece of weather-strip that I'd like to use, as a reproduction is not available. Being that is was made in 1962 it is now a little stiff. Any thought on how to soften it up again so it's shape can be restored, thus installed properly? Thanks, Matt Allyn [Non-text portions of this message have been removed]
