2 Oz - BLI101 - Aerosol Black Laser Ink for Metals Marking - CO2 Laser - Fiber Laser - YAG, Durable, Permanent, High Contrast, Brilliance Laser Inks

I used this as a newbie to laser engraving. It worked really well. I am still experimenting but as a cheaper option, the small bottle is great when you are still learning.

I got this while it was on offer and the results are shown in the picture. The owl was engraved on an aluminium tag and shows with and without using the marking spray. I engraved using an Xtool F1 and the image produced is very nice, this was just a test and not intended to be used so I couldn't comment on how durable the finish is. This product is normally very expensive but if you have a genuine use for it I'd say it's well worth the cost.

We’ll ease of use, that’s pretty good, once you get used to the speed of application, and you don’t really need a lot of the product, for reference I was using both an XTool D1 & a Laserpecker L2, both set to their max, I applied as directed, to 1 sheet of Brass, a sheet of Copper and a Chrome Dog Tag as pictured, the Chrome Dog Tag was excellent no problem with the XTool, did not use Laserpecker, also in the picture the Cogs were XTool on several different settings (score, engrave & cut), and while the brass worked very well, with the XTool, the Laserpecker design failed, and it washed off, and Neither XTool or Laserpecker designs managed to remain on the copper, in its original glossy finish or after I had brushed the finish, all markings washed of, likewise with the brushed Aluminium sheet I tried (not pictured) as my needs are mostly for Chrome, and that worked very well, I’m happy enough, and I know I can mark on Brass, but I couldn’t mark Copper or Aluminium with either of my lasers, as stated in the product description, so yes it’s really easy to use, but at £36 for the tiny aerosol, it’s a tad pricey, I’d give it 3/5 for both performance and value for money

Massively exp for a tiny bottle!!!

I purchased this and happy I did. It is so easy to use. I have a 10w diode laser. You simply coat the metal you want to mark let it dry and let the laser so the rest. Once completed you simply rinse the excess off and that's it.I have tried to scratch the text off but it's on and doesn't mark.

Replaced markings on my oven that were gone using XTool F1.Left a very dark, permanent mark.

Only gave 3 stars because all worked well, I followed the instructions and had a beautiful product. Until it came to hand polishing and the black came off.

Purchased this item as I am trying to engrave dog tags (silver), if I use a black paint it is difficult to remove, I was also looking for an engraving that would leave a black mark, this item seemed to have clicked all of the boxes, however....First to test on glass, sprayed it on, several layers, using my diode 20 watt laser, even though it focused on the residue from the spray, didn't engrave black.Tried it on the silver dog tags, and even though it did engrave black, when rinsed in water, the engraving just came off.just be careful as it's not cheap, it may work for others, but certainly didn't work for me.
