Works great and due to the smaller size it is offered at a better price.

So, if you want to take your lasering game to the next level, look no further than CerMark Ultra Laser Marking Aerosol. Just don't try to use it on painted items, wood, or plastic, unless you want to end up with a hot mess on your hands.

It's crazy expensive, but it makes a much darker and more consistent mark on stainless than anything else I tried. If you're not concerned with the mark being completely black, cold galvanizing spray works pretty good, but there is concern with fumes being toxic (make sure the laser is vented to the outdoors). NOTE: i shook up my little can for literally 1-2 minutes before each use and was able to get every drop of liquid out of the can. Make sure you do that or you might run out of propellant before you run out of product. From what I understand, Cermark is actually a fine glass powder that gets burned into the oxide layer of the metal. You can feel a raised surface there. It's much more prominent than anything else I've tried (plaster of paris, graphite dry lube, cold galvinizing spray). If you want a dark, permanent mark (like 80 grit on an orbital sander for 10 minutes can't get rid of all traces of it), then probably worth it to just bite bullet and buy this stuff.

Ok. So all the reviews I read were either "Great, exactly what I needed" OR "Stay away its no good!" There wasn't a middle ground OR anyone with actual pictures of these "works great" results. So to be clear, this product is to be used with engraving lasers it doesn't matter the brand or the wattage. Its primarily designed for metal but I used it on polyethylene water jugs. When you try to engrave resin or plastic most lasers just turn the surface white. I wanted the design to show up black on the surface of the jug so I bought this spray. When it arrived I though I got the wrong product because the aerosol can was small and only a couple of ounces, I'm sorry to say but the pictures make it look like you're getting an average sized aerosol spray can. I applied the spray to the water jug following the instructions. The spray is an opaque grey and takes about 20 - 30 seconds to dry. Every time I applied it, it only took a single pass to provide full coverage on the hobby surface. Basically it takes very little of the product to prep your product for engraving/marking. Once I worked out the exposure setting for my laser (atomstack x7 pro) these are the results I got. So I would say, it "works great", it does, its VERY expensive per ounce (hence the 3 stars on value) but it DOES do what its supposed to do.

This product does NOT work with all diode lasers. Will NOT work with 14w diode laser. Also, can be purchased through other sources for half the price. Do your research!

Works perfectly only problem to expensive for the amount of product just enough to spray on 24 tequila shots so I need to buy more another recommendation use it at once cover all you material otherwise is going to clog

It worked great for the first few little things, then when I didn't use it and it sat for 2 weeks on a shelf I went to use it again and now it won't spray at all. I shook it and its still full, No clogs or anything. Bought another can in hopes it won't happen again and it was just a random fluke. But for the price you pay for such a small amount you would hope you didn't have to waste it.

Excellent product, perfect for marking/engraving metal, glass and ceramic.
