As for the teflon powder, I didn't fancy ordering from China and having the Old Bill knocking on my door thinking it was marching powder, so got some from a company who specialise in piano servicing and parts, as it's used on the hammers (or whatever the fcuk they are called). Cost me about £15 for 25g IIRC.
I got my MOS2 from eBay. Cost me £8 for 50g, he's put his prices up since, must be all these DIY waxers!
