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 have a Elegoo 20W Diode laser and this product works perfect, even if it states for a CO2 laser. I slowed down my speed (1000) and kept the same power (70%). You can actually feel the engraving that it does, which is far different from the other laser spray that I had bought for about twice the price. I had to try a different brand because that other spray I had worked ok, but it rubbed off with little friction. This product is solid and works like it's supposed to. I would recommend this if you've tried other sprays. I don't usually write reviews but this product did what I needed and if you're having problems like I had, try this.

This works really well and is a fraction the cost of other options. I was able to get good marking on steel and stainless using my 5W diode laser at 100% and very low speed. It's a big enoug can that it'll last me a long time too. Fair warning - if you're not familiar with laser marking sprays this becomes like a powder when it dries and is easy to rub off until you engrave. Once engraved with the laser the mark is pretty permanent!

Great service. Delivered on time. This product is extremely good and consistent on your engravings. Beautiful permanent black mark on stainless steel.

This product works great. Very easy to use and the finished result it’s awesome. Will be purchasing again

Although its not cheap, this product does exactly what its supposed to do and it takes a very thin layer for it to work so really the cost isn't as bad as it seems. I have laser engraved numerous stainless tumblers and I'm currently on my 150th brass medallion and I still have it seems over 1/2 can left. If you've never used this type of spray before it goes on as a liquid but wipes off like its dust. I can run the product under water and this spray comes off with very little effort which is AWESOME.

I have had nothing but issues with this product. It marks the material just as stated there is no issue in that. However, EVERY single can I have ever purchased (5 over maybe 6 months) has stopped spraying material out of the can. I have followed all instructions, kept it in a warm place, even soaked the nozzle in alcohol after every use. No matter what I did I would get maybe 2/3 projects out of the can and that was it. It would not spray out any more product like it ran out of Aerosol. I even contacted Omtech and sent in my patch numbers from the bottom of the cans each and every time and was given the same response. "We had a bad batch and are aware of the issue." Was even sent 2 cans from Omtech and had the same issue over and over. I have given up and will NEVER purchase this again. Go with the Brilliance or XTool makes a spray now, I am going to try those but PLEASE save your money because this product is GARBAGE!

OMG, no words to describe how wonderful this product was. I loved it, the result is 10/10

Doesn’t work exactly as promised but on half of my projects it did fairly decent.
