Been smearing various rubber seals with waterproof grease (Carlube Aquaslip) for years and as far as I know everything has been fine but read something recently which suggested that was not a good idea. Anyone know what Aquaslip is made of and whether it is safe around rubber seals?

Already tried that but no information on it.

There's no single answer, because there are many different types of rubber and different types of grease will be suitable for some and unsuitable for others.

As far as I can tell from Tetrosyl's safety data sheet Aquaslip is an ester oil based grease, which means it's not compatible with natural rubber or styrene based rubber, OK with silicone and nitrile rubber, marginal with everything else.

Cooling system probably not, but the others ought to be oil resistant.

I was under the impression that it was parrafin based.

I always thought vasoline degraded rubber.

Well I suppose that would raise an eyebrow if you're buying your rubbers there too.
