Alternatives to Pica "Pens"

[paulmitchell1984]

Guys and gals

Are there any alternatives to the Pica pens, iv got 2 the thin and the thick, I bought them due to the ability to write on pretty much any surface even wet, which they do, however the "refills" are quite pricey, so just trying to scout out other options,
It can't be a marker pen as such as I need sharp lines, it also can't just be black, as its invisible on steel, the trucks I work on are different colours so different options are also good yellow red black white are what iv had

There used to be some blue dye available to brush on metal. I seem to recall it dried in a reasonable time. The idea was to then use a steel scribe to write on the blue area. When we used that method, it was only straight lines that we were marking out, ready for sawing the steel.

Specre colour was good for marking out on clean smooth metal,

Engineer's Blue.

Engineers blue is basically used fir checking contact between two sufaces,and only to be applied extremely thinly for accurate readings, Spectre colour is solvent based? and dries very quickly to allow fine marking with a scriber etc,
