diff grease and threadlock for 1/10 electric kit

[Riblau]

Hey guys,

I'm starting a mad monkey build this weekend and in the instructions it says I need 'diff grease' and 'screwlock'...

I don't have immediate access to a hobby shop, so was wondering if there is a substitute for each I can pick up from Robert Dyas or Homebase that would do? It's my first buggy build so I'm not too fussed if it's not the perfect grease or whatever.

Also, the kit came with a small jar of what looks like vaseline. Could this be that it includes the grease I need but the instructions are wrong as I can't see this jar referenced in the instructions.

Cheers,
Riblau
