Dykem Layout Fluid Blue, 8 oz. Can and Brush in Cap. Machinist Dye for Metal Layout Work, The Perfect Marking Fluid for Machinist, Metal and Metalworking (1 Each)

Makes good bluing, Just mix with denatured alcohol and wipe on with a rag. Have been using for years in paint prep to see where areas need sanding or filling and in final prep to make sure everything has been sanded.

If you'e looking at it, you know what it's for. It works and does what it is supposed to do.

Paints on well to easy layout with a scribe or for seeing where two things contact. Dries quickly if you don't put on too thick. Holds on strong until you use solvent to easily remove it.

Exactly as described however the shipping took almost a month and they couldn’t locate it for a while in the system

This is awesome to have when lapping valves on an engine

Layout fluid serves all sorts of uses in the shop. It is a traditional coating for metal to be scribed and machined.

Leaked in in shipping, not totally empty, but quite the mess.

Awesome stuff. Makes layout way easier to see
