Steve and listers;
I'm not a chemical engineer, but have been in plastic molding business for
what seems like 100 years. In the 50s, I was told silicone (which is in
Armor-all, )is really like a bunch of mini-scopic ball bearings, gets into
the
structure of plastics and rubber and tears the structure apart. I made the
mistake of putting a drop of silicone on threads of a micrometer and it galled
the threads immediately and permanently, so I know it has a presence that can
fill up space. That can cause cracking in rubber tires acting as a wedge to
separate the material basic structure. For what it's worth - - - -
