The original Stuarts Micrometer Engineer’s Marking Blue is a non-abrasive easily-spread marking paste containing a high concentration of pure Prussian blue in a grease base. Used in engineering to illustrate contact areas between mated surfaces, engineers blue can also be thinned with meths to make marking out blue, a strong dye that colours components making scribed layout lines easier to see.
Apply sparingly, Stuarts Micrometer engineer’s blue has a very high pigment content so a little goes a very long way indeed.
Engineers blue can be removed with methylated spirit.
