OMTechLaser Marking Spray, 13oz Aerosol Black CO2 Spray for Laser Engraving Metal, Laser Ink for Aluminum Stainless Steel Brass,Metal Laser Marking Fluid for CO2 Laser Engravers

Awesome product!!

As of now this is the 3rd brand that I’ve bought and is been the best out of the 3

The spray worked great. I used it on a brass coin l purchased from Amazon. And was able to get a nice etching with my diode laser. Very happy.

I love it, now I can run my diode laser at a higher speed and not worry it won’t mark metal. like it bc it’s not smelly like other homemade chemicals I hear people using, washes off so so easy, I use water and sometimes I just wipe off with a damp cloth and that it, pretty awesome. the engraving comes out great! You can feel it over the material instead of “carved in” which is fine by me. i use it on my diode laser although it says for CO2 but works awesome for me. I’ve engraved tiny artwork on jewelry and rings and this comes out great

So from the image I attached it looks like it didn't work. I tried Greyscale and yes it didn't work on brass. However, I tried again and it worked if you did black and white.I will also make a note it worked on Stainless Steel. I just don't have a picture of it.I will warn you it will heat up the metal as well so be careful of handling.

Its really hard to get this to burn good

I'm so thankful they make a good quality product at an accessible price. Quick to use, did extremely fast.

Works ok even tho I'm struggling with my settings on my poor 5w laser
