I am not a chemistry type, but was curious.

From Wiki on Siloxane:

http://en.wikipedia.org/wiki/Siloxane

Dow Corning on their VC automotive use product:

One example of a polymerized siloxane on Wiki page is
polydimethylsiloxane. DC's description of the VC product is
"Dimethyl-based viscous coupling fluid".  "Silicone Oil"  shown here:

http://www.thesage.com/catalog/products/Dimethicone.html

says "polydimethylsiloxane"

Could DC's product be the right stuff for Vanagon VC? If so, group buy?

Here's a Vanagon page by Drew on VC. I'm sure most have seen it, but I hadn't.
