Castrol red rubber grease

["jspeiser" <jspeiser@erols.com>]

Am rebuilding the rear springs on my TD.  Before assembling with new rubber
pads between the spring ends, I'd like to lube the pads with Castrol red
rubber grease, which is easily obtained in the UK for restoration work, but
I haven't seen it in the USA -- does anyone know where to get it here, or
of an alternative grease that's OK to use on rubber?  Moss doesn't carry it
- I checked.  Thanks!
