xTool Black Laser Marking Spray, 1pc, 8.5 oz - Advanced High Contrast Formula for CO2, Fiber & Diode Laser Engravers - New & Improved Version

I run a laser engraving and cutting business and have used this spray on both metal and plastic with excellent results. It’s very easy to apply — just make sure to use it outside or in a well-ventilated area, as the fumes are strong. One thing to note is that while it's called a “black” laser marking spray, it actually sprays out with a yellow tint. That said, the final engraved marks come out black, crisp, and clean, exactly as expected. It doesn’t degrade the quality of the materials I’m engraving on, and it’s been surprisingly long-lasting — I’ve been using the same can for a couple of months across multiple projects, and there’s still plenty left. Definitely worth the investment for anyone doing precision laser work.

5 stars for quality, ease of use 5 stars for coverage 4 stars for cost effectiveness Can is smaller than other brands for the same price, but I figured I’d give it a shot since it’s the xtool brand. Worked well enough, but the Cermark brand is just fine in a bigger can for less money. Might not cover as well as xtool brand and require a couple more passes. Xtool brand did a great job to cover effectively

Pricey, but works well. Glad we don't need it often. Try a few of them to see what works best.

I run a laser engraving operation and have tried a few different marking sprays over the years. This xTool spray gives a noticeably high contrast black mark on metals and glass. Application is easy, just spray a light coat, let it dry, engrave, then wipe clean. Works well on stainless steel and aluminum. One can goes a long way if you apply thin coats. The only thing to watch is that it can smell pretty strong so make sure you have ventilation. Results are crisp and the marks are durable after wiping. Much better contrast than some cheaper alternatives I have tried.

Best spray on the market , my jibs have been comjng out soo much better with this then the black paint markers.

Works awesome on glass when using a diode laser. Made amazing etchings on the glasses I was engraving. Washed off really easily with just a little water. Easy to use if you follow the instructions just spray an even coat on the part youre engraving and let it sit for 10-30 mins and it is ready to engrave your parts.

Love this product, easy to use, nozzle didn’t clog (which I’ve had issues with other brands doing this). I used it on a ceramic plate for a wedding gift and the image came out beautifully. I used a vintage preset for the image and it was exactly what i wanted! Will be purchasing again in the future.
