True

Red rubber grease is based on vegetable oil - designed to not rot rubber and be suitable for use with glycol brake fluids ( Dot 3,4 and 5.1 )

Mineral oil greases such as Lithium multipurpose can damage the rubber seals.

DESCRIPTION
Castrol Red Rubber Grease is a medium consistency grease based on a vegetable oil and a synthetic gelling agent. It is fortified with additives to improve its resistance to oxidation and corrosion.

APPLICATION
Castrol Red Rubber Grease is formulated for rubber to rubber lubrication where any effects such as hardening or swelling of the rubber must be avoided. It can therefore be used on automotive hydraulic brake and clutch components where compatibility with natural rubber and SBR seals is involved. It may also be used to assist assembly of natural and synthetic rubber components for automotive brake and clutch systems and suspension units.

BENEFITS
S Compatible with natural and synthetic rubber S Good anti-corrosion properties

plenty of RRG on Ebay
In theory, you could use Mazola, or spry crisp and dry ... would be a bit dribbly though

Hmmm, no mention of its suitability with latex and any danger of damage to skin

Dunno, I try to keep it off my hands.

what about using that silicone grease? We use it to assemble lipseals where i work.

I always use nitrile gloves when handling greases
