I almost laughed out loud when I read: "I got on very well with a lady who supplies leather,"
what you really need now you have hard chrome king pins is a machined recess in the bottom of the stub axle to take a motorcycle type fork seal - you could then pump in some heavy oil - I have heard of STP being used on king-pins - although I will switch from LM to CL for my standard set up - Castrol CL is about the consistency of golden syrup and is apparantly less likely to absorb moisture than LM when used in low temp areas
