Dykem steel blue layout fluid

[NFATrustGuy]

I bought some years ago when I started reloading. Ran into situations at the indoor range re: whose brass belonged to whom. I started marking mine with blue or red to make it easy. Also helped me pick out my 9mm versus all the danged .380. I purchased mine via Amazon.

I use a combination of sharpie and soot from a candle when fitting precision parts

That's where I got mine.

I got my last bottle from Enco, which is now MSC. As mentioned, a sharpie works pretty well and leaves a thinner coat. The candle soot is even thinner, for lapping Garand bolts and whatnot.

Pretty sure Grainger has it.

Forgive my ignorance, but what is this product used for? I've read the comments above and still don't understand what it is/does.

I was reading through this entire thread hoping to find the answer as well.

From the Amazon link earlier in the thread;

Product description
The Dykem 80300 Steel Blue layout fluid is used to coat metal to provide a glare-free, uniform color so scribes appear clear and sharp. This product is a transparent, blue stain. It can also be used on other surfaces to reveal defects or pinholes, or view gear tooth contact pattern. It provides a thin film without cracking or chipping and dries in minutes for convenience. It comes in a bottle containing 4 oz. of fluid. The bottle has a brush in the lid that can be used to apply the solution.

Scribing a mark on metal normally has very little contrast (usually steel which is silver on silver). This product colors the surface metal blue so a scribe mark on the metal leaves a sharp, clean line (the color of the underlying metal). For the use in gear contact, the color will wear where the teeth engage each other.

It’s a thin semi transparent paint that you spray or brush on to metal for marking out patterns. When you scratch it with a scribe it leaves a crisp clean mark so you can see your lay outs clearly. You’ll see it used a lot in gun smithing also.

Fastenal usually carries it as well. I would avoid the spray cans of Dykem. I swear half way through a can it just stops spraying. Don’t think I’ve ever gotten through a whole can. I have switched over to FMT layout fluid in a spray.
