OMTech Laser Marking Spray, Metal Laser Marking Fluid for CO2 Laser Engravers, 13oz Aerosol High Contrast Black Spray for Laser Engraving Metal, Laser Ink Agent for Aluminum Stainless Steel Brass More

I bought the spray multiple times for my laser engraving projects. Material dries quickly and goes on smooth. All my projects have turned out excellent and I’ve had no issues. The price is worth the product when you know it’s gonna be correct every time.

So far it’s working good. Nice dark engraving, even on aluminum.

This stuff is awesome! It even worked on black stainless steel for a tone on tone effect. I used a diode laser btw. I wish it wasn't so expensive, but it is easy to use and works, so thats really my only complaint.

Laser marking on metal for hobby lasers that are not powerful enough to cut into the metal is a great workaround. You should test before setting the speed/intensity to avoid ruining your project. Ask me how I know. Works well once you have done your research. Durable finish

Works exactly as described.

Good product, it does what it is supposed to do, the biggest surprise is that it has a white cap and i want it to be black like in the main picture, but when laser activated, the "burnt" area became black permanently.

Perfect for engraving

Did not work. We could be doing it wrong but, we followed directions to the T it just doesn’t work for us. The price was way too high. I figured with the high price it would at least work but, it didn’t.
