Silicon grease applications

Someone had posted that silicon grease may damage rubber.

I use this stuff:

Also known as "dielectric grease" because it is nonconductive. Use on electrical connections to prevent corrosion, and on spark plug ceramic insulators so the boots don't stick to them.

I wouldn't use it on window channels because dirt can stick to it and gum them up eventually. I use spray-on powdered graphite for that application.

BTW, it's SILICONE with an E. Silicon is what transistors and computer chips are made from. Silicon Valley is where high-tech companies are located. "Silicone Valley" is a name my grandfather jokingly used to refer to Hollywood. Remember that and you'll never get the two materials confused.

I use the grease on oil filter, valve cover gaskets and recently on the filler tubes (sparingly) on the fuel tank filler neck in my’02 F-350.

I keep a nasty fingerprinted tube with my brake tools and clean tube with my electrical stuff. I've never seen it hurt any rubber or soft parts, but it doesn't mix well with the synthetic version on brake applications and becomes glue... a nice late 80's discovery when NAPA sold us on trying the newer product.

I've used that stuff on a variety of hard rubber gaskets, car and house related. Never any problems year after year. But I wouldn't think it would be good for more porous foam like trunk weather-stripping (or similar). That would get sticky and gummy without cleaning. Maybe that what they mean about "damage". The rubber is still there it just acts differently...not good for its intended purpose.

I sometimes use it sparingly on door seals on our DD vehicles, to make sure that the doors don't get frozen shut in the winter. Especially on newer vehicles that don't have gutters over the doors, doors stuck shut in the morning is a problem when the temp is hovering around freezing. I agree that silicone can make the seals feel gummy.
