I see lots of rubber grease now....!
Good stuff but next to impossible to find in Canada and the USAs anymore. I did find some somewhere in small quantities, but having to pay $15-20.00 for 2 Oz or so and then more than that for shipping to Canada, not cost effective.
Good stuff for rubber parts on fuel injection systems, unlike sillycone products will not pollute an expensive O2 sensor.
Big can shipped from the UK was less than $20.00. When I looked there was someone selling it by the tablespoon on Fleabay.
Castrol makes a similar product overseas, "Castrol Red Grease".
Castor grease.....well Castor is French for Beaver......
