PK,
I have no idea if it's available in the UK, but if it's not, there must be something just like it. Machinists use it all the time, and there are tons of machinists in the UK.
Dykem is basically just lacquer paint. It smells pretty bad when you put it on, but it dries VERY fast and then there's no smell. I'm sure that just about anything similar would work just fine - you want something that won't 'flake' as you scratch it, and something that will resists FeCl (which Dykem does just great).
