Winter gloves

This may be a stupid idea, but before I go and waste some money testing it out I thought I'd ask.

As someone that suffers badly with cold hands and quite severe Reynauld's, would I start to benefit from giving my hands a good rubbing with winter embrocation before heading out on the bike? Would it heat my hands, improve circulation or just do nothing? I appreaciate that it may be a bit weird and slimy, but that may be a price worth paying.

Slap me if you've heard this a thousand times before but have you tried lobster gloves?
I've just got these http://www.tenn-outdoors.co.uk/cold-weather-windtex-lobster-split-finger-cycling-glove--black-sml (although when they were on offer for £5) and so far no numbness at all. I know it's not been that cold yet but the fact that there is ample space in the glove for and no pressure on my fingers seems to have helped so far.
