My tube of the shin etsu (sp) seems like it will last for a good 20 years.

 

this is a really noob question but i have only had my s for about 2 months now but what is this grease and what exactly is it for?

 

Re-read the first post.

 

The original question was if "silicone spray" would be as good. Nothing was asked about "silicone grease". I agree that silicone grease would work also.

 

For your rubber seals, to prevent them from drying out and/or squeaking.

 

^^ so it is for all the rubber seals on the whole car thanks i just wasnt sure if it was one spot in particular

 

I don't buy that any silicone grease would work just as well. The term "silicone grease" covers an awfully wide range of polymers that happen to contain silicon in a carbon chain. I use a varietu of silicone products at work that have widely differing properties.

 

100% silicon grease is 100% silicon grease. Industrial greases will be slightly different, but the tub you buy at the hardware store will be the same at all of them. We're talking about a ambient temperature rubber seal not a high pressure, high temperature gasket. It's just like cleaning all the chassis boots and mounts. Any name brand silicon product will work.

 

Before you try to substitute Shin-Etsu grease with silicone spray or something else just remember that it's the only grease/lubricant left that American Honda has to bring in from Japan because they themselves have not found a locally produced product that is a worthy replacement.
Not saying silicone grease won't work but for whatever reason it doesn't hold up or work as good as Shin-Etsu so you may have to apply it more often.

 

Here you go buddy!!
