OMTech Laser Marking Spray, Metal Laser Marking Fluid for CO2 Laser Engravers,4X 8oz Aerosol High Contrast Black Spray for Laser Engraving Metal, Laser Ink Agent for Aluminum Stainless Steel More

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.

Works INCREDIBLY well. I have used magic erasers, abrasive material and washed in a dishwasher and it does not phase the engraving. I would absolutely buy this product again!

I use it with my co laser for stainless and glass. Purs a nice black image on the SS when you use enough power. Works on glass as well and is easier than masking tape.

Creates dark marking as promised on stainless steel. Even tested on glass and frosted it. Love this product for my laser work.

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

This stuff works great! Really marks the laser engraving to the metal! It’s a big can, will definitely do plenty of engraving with just one can!

Works well with 45w diode

Perfect. Product is exactly as described.
