Review: Works perfectly and the final looks is beautiful! - Este spray es una herramienta altamente recomendable para cualquiera que tenga una láser CO2, he podido grabar varios elementos de metal y quedan hermosos. El valor recibido por lo que pagué es justo. Es fácil de limpiar con agua después de grabar y ya ví que hay otro spray en color rojo que voy a probar. Recomiendo al aplicar hacerlo en un lugar aireado y usar mascarilla porque el spray parece una espuma pero se seca y se vuelve polvo al contacto con el aire. Se debe dejar secar bien antes de grabar. This spray is highly recommended for anyone who owns a CO2 laser; I've been able to engrave several metal items, and they turned out beautifully. I feel I got good value for my money. It’s easy to clean off with water after engraving, and I’ve seen that there’s another spray in red that I’m going to try. I recommend applying it in a well-ventilated area and wearing a mask, because the spray looks like foam but dries and turns into dust when it comes into contact with the air. You should let it dry thoroughly before engraving. Review: From “Can’t Mark Metal” to Clean, Professional Results - I didn’t expect a spray can to change what my laser could do—but this one kind of did. I’ve always known my CO₂ laser isn’t meant for bare metal. Stainless, aluminum, brass—normally it just reflects or lightly etches at best. After trying the OMTech Laser Marking Spray, I went from “not possible” to clean, dark engravings that actually look intentional. The Moment It Clicked The first time I wiped off the excess coating and saw a deep black mark left behind, it honestly felt like cheating. It bonds during the engraving process, so you’re not just discoloring the surface—you’re leaving a durable mark. It’s More About Technique Than the Product This isn’t a “spray and magic happens” situation. What made the biggest difference for me: Light, even coats (too thick = muddy results) Letting it fully dry before engraving Dialing in power/speed settings per material Once I figured that out, results became repeatable. Where It Shines (Literally My Use Cases) I’ve gotten the best results using it for: Tool labeling (no more stickers peeling off) Small metal tags and plates Custom branding on parts It’s especially satisfying on stainless—super crisp contrast. Not Perfect—But Close Enough It can get messy if you overspray, and cleanup is part of the process. But compared to buying a fiber laser? This is a no-brainer workaround ## Features - Laser Marking Spray: OMTech's laser marking spray’s innovative formula allows creation of high contrast, permanent black designs on bare metals with your 25W and above CO2 laser engraver, or more vivid designs with your fiber laser. Please note that the spray initially appears white but turns black after laser engraving - Wide Application: Our laser marking fluid works with most metals including aluminum, stainless steel, brass, and many others, letting you personalize jewelry, customize tumblers, serialize tools, and much more - Even Coating: The 8 fluid ounce aerosol can features a clog proof nozzle that sprays the fine-grained agent with even force, leaving a thin and smooth coat of our marking agent on your bare metal surface - Fast Drying: The cadmium-free metal marking ink dries in under 5 minutes, or in only 2 minutes with a hot air blower, ensuring hassle-free and efficient operation even for batch production - Easy Washing: Once your marking is complete, the unmarked excess black spray can be washed off your item with a simple rinse, so you can enjoy and start selling your fresh and unique design right away ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #3,938 in Arts, Crafts & Sewing ( See Top 100 in Arts, Crafts & Sewing ) #7 in Jewelry Making Engraving Machines & Tools | | Customer Reviews | 4.5 out of 5 stars 889 Reviews | ## Images ![OMTech Laser Marking Spray, 4pcs 8oz, Black Marking for CO2 Laser on Metal - Image 1](https://m.media-amazon.com/images/I/71kfWBquaAL.jpg) ![OMTech Laser Marking Spray, 4pcs 8oz, Black Marking for CO2 Laser on Metal - Image 2](https://m.media-amazon.com/images/I/61sLk2TzAGL.jpg) ![OMTech Laser Marking Spray, 4pcs 8oz, Black Marking for CO2 Laser on Metal - Image 3](https://m.media-amazon.com/images/I/71ieqsu1yVL.jpg) ![OMTech Laser Marking Spray, 4pcs 8oz, Black Marking for CO2 Laser on Metal - Image 4](https://m.media-amazon.com/images/I/81NbSbK6+oL.jpg) ![OMTech Laser Marking Spray, 4pcs 8oz, Black Marking for CO2 Laser on Metal - Image 5](https://m.media-amazon.com/images/I/71GtmNfbRAL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works perfectly and the final looks is beautiful! *by S***. on July 3, 2026* Este spray es una herramienta altamente recomendable para cualquiera que tenga una láser CO2, he podido grabar varios elementos de metal y quedan hermosos.

It is super easy to apply, super easy to remove and left a nice frosted white finish on glass. We haven't tried it on metal yet, but will soon. The only complaint I have is that it is 40 bucks a can, but other than that it is awesome. Goes on nice and smooth, dries quickly, works well and rinses right off.
