## Description

STUARTS MICROMETER ENGINEERS BLUE Tube off USED IN MARKING OUT IN THE WORKSHOP/GARAGE FOR LOCATING HIGH SPOTS ON STEEL SURFACES IN THE GARAGE WHEN CHECKING VALVE SEATS ETC, SO MANY USES

Review: Good quality non-drying engineer's blue - I used it for checking fit of a MT3 taper adapter in a Chinese mini-lathe spindle. A tube is less messy than a tub when you only want a small quantity of blue at a time. Worked exactly as expected and confirmed most of the runout was due to a damaged spindle tape
Review: Not bad arrived quite quickly to UK address. - Not bad arrived quite quickly to UK address and seems descent quality for the price. Spreads ok but A little brush suitable for applying would be a good add on purchase and I for one would get a few of them.
