CerMarkULTRA Laser Spray Marking Aerosol, 12oz

This works really really well at helping to create a mark on objects with a diode laser. Simple to use and washes right off with water leaving the etching in tact. I have it 5 stars because it works great BUT it is really high priced.

Well, there are a number of other laser marking sprays out there for less, this is the only one I’ve found that says it will mark glass as well as metal. It does both very well. The excess also cleans off easily with just warm water. The 12 ounce can has lasted for over two dozen applications on pint glasses. It is not empty yet. So if you want extra sharp, black laser etching on glass, this is the product for you.

I like this cermark and am happy that it works so good on glass. I haven't tried it on other materials yet. It makes the etching come out pure black as seen in the photos. It washes off with water and only needs one coat so this can should last for a long time. I just wish it wasn't 100 dollars a can. Crazy expensive. I will be trying cheaper alternatives in the future to keep costs down.

Works great

The spray comes out uneven and chunky at times. When engraving this shows up and makes the product look terrible. Waste of money

Works as advertised EXCEPT the spray nozzle was missing. Amazon would not let me return the item but did refund the cost of the item. I finally found a nozzle from a can of spray paint that would work except it doesn't dispense the product in fine enough of a mist to avoid sputter splotches on the work surface. Pretty expensive for what it is.

This is definitely the best marketing spray there is, however, in my last order at 94 or five dollars a pop, the nozzle clogged about a third way through the can, and despite my effort to free it soaking overnight in acetone, etc., high compressed air, I have had no success being able to get the rest of the can.

This is the best of the best... however, I do not think it is a great value for the money. I have found other laser marking products that are equally as good for half the price. I recommend this product for laser engraving of metals but would suggest that one research what is available.
